As a first step towards migrating davinci platforms to use common clock framework, replace all instances of clk_enable() with clk_prepare_enable() and clk_disable() with clk_disable_unprepare(). Until the platform is switched to use the CONFIG_HAVE_CLK_PREPARE Kconfig variable, this just adds a might_sleep() call and would work without any issues. This will make it easy later to switch to common clk based implementation of clk driver from DaVinci specific driver.

Previously the code only acquired spinlock after increasing / decreasing the usecount value, which is wrong. This leaves a small window where a task switch may occur between the check of the usecount and the actual wakeup / sleep of the domain.

s3c2440_clk_add is a subsys_interface method and calls clkdev_add_table, which is marked as __init. The modpost script complains about this because we must not call an __init function from a function in the .text section, and we cannot reference an __init function from a subsys_interface pointer. I have verified that the only code path into s3c2440_clk_add() is from "int __init s3c2440_init(void)", so s3c2440_clk_add can be marked __init_refok instead. Without this patch, building mini2440_defconfig results in: WARNING: vmlinux.o(.text+0x9848): Section mismatch in reference from the function s3c2440_clk_add() to the function .init.text:clkdev_add_table() The function s3c2440_clk_add() references the function __init clkdev_add_table(). This is often because s3c2440_clk_add lacks a __init annotation or the annotation of clkdev_add_table is wrong.

Commit 9e3c0066 (ARM: dts: imx6q-arm2: add pinctrl for uart and enet) defines NANDF_CS pins as gpio in 'hog', assuming these two pins are always used by usdhc3 in gpio mode as card-detection and write-protection on ARM2 board. But it's not true. These pins are shared by usdhc3 and gpmi-nand. We should have the pins functional for gpmi-nand when usdhc3 is disabled. Move the pins out of 'hog', so that pins only work in gpio mode as CD and WP when usdhc3 is enabled, and otherwise they are available for gpmi-nand.

In init/main.c, we issue: kernel_thread(kernel_init, NULL, CLONE_FS | CLONE_SIGHAND); This creates a new thread, which falls through to the ret_from_fork assembly, with r4 set NULL and r5 set to kernel_init. You can see this in your oops dump register set - r5 is 0xc0344555, which is the address of kernel_init plus 1 which marks the function as Thumb code. Now, let's look at this code a little closer - this is what the disassembly looks like: c000d180 <ret_from_fork>: c000d180: f03a fe08 bl c0047d94 <schedule_tail> c000d184: 2d00 cmp r5, #0 c000d186: bf1e ittt ne c000d188: 4620 movne r0, r4 c000d18a: 46fe movne lr, pc <-- XXXXXXX c000d18c: 46af movne pc, r5 c000d18e: 46e9 mov r9, sp c000d190: ea4f 3959 mov.w r9, r9, lsr #13 c000d194: ea4f 3949 mov.w r9, r9, lsl #13 c000d198: e7c8 b.n c000d12c <ret_to_user> c000d19a: bf00 nop c000d19c: f3af 8000 nop.w This code was introduced in 9fff2fa0 (arm: switch to saner kernel_execve() semantics). I have marked one instruction, and it's the significant one - I'll come back to that later. Eventually, having had a successful call to kernel_execve(), kernel_init() returns zero. In returning, it uses the value in 'lr' which was set by the instruction I marked above. Unfortunately, this causes lr to contain 0xc000d18e - an even address. This switches the ISA to ARM on return but with a non word aligned PC value. So, what do we end up executing? Well, not the instructions above - yes the opcodes, but they don't mean the same thing in ARM mode. In ARM mode, it looks like this instead: c000d18c: 46e946af strbtmi r4, [r9], pc, lsr #13 c000d190: 3959ea4f ldmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d194: 3949ea4f stmdbcc r9, {r0, r1, r2, r3, r6, r9, fp, sp, lr, pc}^ c000d198: bf00e7c8 svclt 0x0000e7c8 c000d19c: 8000f3af andhi pc, r0, pc, lsr #7 c000d1a0: e88db092 stm sp, {r1, r4, r7, ip, sp, pc} c000d1a4: 46e81fff ; <UNDEFINED> instruction: 0x46e81fff c000d1a8: 8a00f3ef bhi 0xc004a16c c000d1ac: 0a0cf08a beq 0xc03493dc I have included more above, because it's relevant. The PSR flags which we can see in the oops dump are nZCv, so Z and C are set. All the above ARM instructions are not executed, except for two. c000d1a0, which has no writeback, and writes below the current stack pointer (and that data is lost when we take the next exception.) The other instruction which is executed is c000d1ac, which takes us to... 0xc03493dc. However, remember that bit 1 of the PC got set. So that makes the PC value 0xc03493de. And that value is the value we find in the oops dump for PC. What is the instruction here when interpreted in ARM mode? 0: f71e150c ; <UNDEFINED> instruction: 0xf71e150c and there we have our undefined instruction (remember that the 'never' condition code, 0xf, has been deprecated and is now always executed as it is now being used for additional instructions.) This path also nicely explains the state of the stack we see in the oops dump too. The above is a consistent and sane story for how we got to the oops dump, which all stems from the instruction at 0xc000d18a being wrong.

The prima2 platform advertises needing no mach/gpio.h header file, but its pinctrl driver now has a sirfsoc_gpio_set_pull function that uses constants defined in arch/arm/mach-prima2/include/mach/gpio.h, which fails to build. Fortunately, the sirfsoc_gpio_set_pull is not used anywhere in the kernel, so we can safely remove it. Any out of tree drivers using it will have to be converted to use proper pinctrl functions to do the same. Without this patch, building prima2_defconfig results in: drivers/pinctrl/pinctrl-sirf.c: In function 'sirfsoc_gpio_set_pull': drivers/pinctrl/pinctrl-sirf.c:1331:7: error: 'SIRFSOC_GPIO_PULL_NONE' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1331:7: note: each undeclared identifier is reported only once for each function it appears in drivers/pinctrl/pinctrl-sirf.c:1334:7: error: 'SIRFSOC_GPIO_PULL_UP' undeclared (first use in this function) drivers/pinctrl/pinctrl-sirf.c:1338:7: error: 'SIRFSOC_GPIO_PULL_DOWN' undeclared (first use in this function) Signed-off-by: NArnd Bergmann <arnd@arndb.de> Acked-by: NBarry Song <Baohua.Song@csr.com> Signed-off-by: NLinus Walleij <linus.walleij@linaro.org>

As suggested by Andrew Morton: This is a pet peeve of mine. Any time there's a long list of items (header file inclusions, kconfig entries, array initalisers, etc) and someone wants to add a new item, they *always* go and stick it at the end of the list. Guys, don't do this. Either put the new item into a randomly-chosen position or, probably better, alphanumerically sort the list. lets sort all our select statements alphanumerically. This commit was created by the following perl: while (<>) { while (/\\\s*$/) { $_ .= <>; } undef %selects if /^\s*config\s+/; if (/^\s+select\s+(\w+).*/) { if (defined($selects{$1})) { if ($selects{$1} eq $_) { print STDERR "Warning: removing duplicated $1 entry\n"; } else { print STDERR "Error: $1 differently selected\n". "\tOld: $selects{$1}\n". "\tNew: $_\n"; exit 1; } } $selects{$1} = $_; next; } if (%selects and (/^\s*$/ or /^\s+help/ or /^\s+---help---/ or /^endif/ or /^endchoice/)) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } undef %selects; } print; } if (%selects) { foreach $k (sort (keys %selects)) { print "$selects{$k}"; } } It found two duplicates: Warning: removing duplicated S5P_SETUP_MIPIPHY entry Warning: removing duplicated HARDIRQS_SW_RESEND entry and they are identical duplicates, hence the shrinkage in the diffstat of two lines.

Upgrade nomadik pinctrl driver to enable selection of other alternate-C[1-4] functions on some specific ux500 SoC pins. Handling of those functions is done thanks to PRCM GPIOCR registers. This was previously managed in PRCMU driver and it was not really convenient. Idea is to provide a common way to control all alternate functions. Note that this improvement does not support the old-fashioned way used to control nomadik pins, namely the "nmk_config_pin()" function and its derivatives.
