Several init/setup functions passed the PCI BAR resource start address to ioremap_nocache() via an unsigned long. This caused address truncation for a 32-bit device mapped above 4 GiB (i.e. the CPU interacts with the device via a translated address), which resulted in a kernel panic. This patch replaces all of the instances of intermediate variable use with pci_ioremap_bar() to ensure the full resource_size_t start address is used and that ioremap_nocache() is still called. The kernel panic (Exar XR17V358 PCIe device on a Freescale P2020 SBC): Machine check in kernel mode.

We don't really need to perform the ioremap "on demand" so it's simpler just to do it from the probe function.

The original non-DT bcm63xx clk code ignores the struct device argument and looks up a global clock name. DT platforms, by contrast, often just use a phandle to reference a clock node with no "clock-output-names" property. Modify the UART driver to support both schemes.

This device was originally supported on bcm63xx only, but it shows up on a wide variety of MIPS and ARM chipsets spanning multiple product lines. Now that the driver has eliminated dependencies on bcm63xx-specific header files, we can build it on any non-bcm63xx kernel. Compile-tested on x86, both statically and as a module.

We need to issue a reset if we ever change the value of the IPR register on DM hardware. If we don't reset the hardware the RX stale interrupt never triggers and the only way to trigger an RX handling event is by filling up the fifo. This causes things like getty to not work so well considering it might change the baud rate a few times. Fix this by moving the reset on startup and any reprogramming required after the reset to be after we change the baud rate.

To properly support sysrq on uartDM hardware we need to properly handle break characters. With the DM hardware the fifo can pack 4 characters at a time, where a break is indicated by an all zero byte. Unfortunately, we can't differentiate between an all zero byte for a break and an all zero byte of data, so try and do as best we can. First unmask the RX break start interrupt and record the interrupt when it arrives. Then while processing the fifo, detect the break by searching for an all zero character as long as we recently received an RX break start interrupt. This should make sysrq work fairly well.

Dedicated CTS and RTS pins are unusable together with a lot of other peripherals because they share the same line. Pinctrl is limited.

Russell King: The only thing which the .get_mctrl method is supposed to do is to return the state of the /input/ lines, which are CTS, DCD, DSR, RI. The output line state is stored in port->mctrl, and is added to the returned value by serial_core when it's required. RTS output state should not be returned from the .get_mctrl method. This patch removes ctrl variable from mxs_auart_port and removes useless reading back RTS line. The ctrl variable in mxs_auart_port duplicated mctrl, member of uart_port structure in serial_core.h. The removed code from mxs_auart_set_mctrl() and mxs_auart_get_mctrl duplicated uart_update_mctrl() and uart_tiocmget() in serial_core.c.

This patch swaps the use "tail" and "head" to fit the semantic of the linux circular buffer documentation: - head: the point at which the producer (the DMA controller) inserts items. - tail: the point at which the consumer (the serial framework) finds the next item. Besides the former code of the rx ring buffer didn't manage the case where head < tail, which might lead to loss of data. To fix this bug the data are now sent from the DMA buffer to the serial framework in two steps: 1 - First, we test if head < tail. If so, we copy the data from tail to the end of the DMA buffer then reset tail to zero. 2 - Finally, we copy data from tail to head then set tail to head. In addition, since tty_insert_flip_string() may now be called twice, atmel_flip_buffer_rx_dma() becomes less efficient than moving the calls dma_sync_sg_for_cpu(), dma_sync_sg_for_device(), tty_insert_flip_string() and tty_flip_buffer_push() directly into atmel_rx_from_dma().

Increase the maximum number of consoles possible to 10 since DRA7 now has the maximum number of consoles possible. without doing this, for example, enabling DRA7 UART10 results in internal data structures and console cannot match up and we endup with a crash as follows: [ 1.903503] omap_uart 48424000.serial: [UART-1]: failure [serial_omap_probe]: -22 [ 1.911437] omap_uart: probe of 48424000.serial failed with error -22 [ 1.920379] Unable to handle kernel NULL pointer dereference at virtual address 00000004 [ 1.928894] pgd = c0004000 [ 1.931732] [00000004] *pgd=00000000 [ 1.935485] Internal error: Oops: 5 [#1] SMP ARM [ 1.940338] Modules linked in: [ 1.943542] CPU: 1 PID: 12 Comm: kworker/1:0 Tainted: G W 3.18.0-rc1-00001-g8821bc4-dirty #6 [ 1.953521] task: ed8a2d00 ti: ed8a4000 task.ti: ed8a4000 [ 1.959197] PC is at process_one_work+0x38/0x4a4 [ 1.964050] LR is at 0x0 [ 1.966705] pc : [<c00548e0>] lr : [<00000000>] psr: 40000093 [ 1.966705] sp : ed8a5ea8 ip : ed8a5ec8 fp : eeb9abc0 [ 1.978759] r10: ed8a4000 r9 : 00000008 r8 : ed842458 [ 1.984252] r7 : 00000000 r6 : eeb9abc0 r5 : ed842440 r4 : edbf26a8 [ 1.991119] r3 : 00000000 r2 : 00000000 r1 : 00000000 r0 : 00000000 [ 1.997985] Flags: nZcv IRQs off FIQs on Mode SVC_32 ISA ARM Segment kernel [ 2.005767] Control: 10c5387d Table: 8000406a DAC: 00000015 [ 2.011810] Process kworker/1:0 (pid: 12, stack limit = 0xed8a4248) [ 2.018371] Stack: (0xed8a5ea8 to 0xed8a6000) [ 2.022949] 5ea0: 00000001 00000000 60000093 c008346c 00000001 ed8a5ec8 [ 2.031555] 5ec0: c0054de4 eeb9abc0 ed8a4000 ed842458 00000008 ed8a4000 eeb9abc0 ed842440 [ 2.040161] 5ee0: eeb9abc0 eeb9abf0 ed8a4000 ed842458 00000008 ed8a4000 eeb9abc0 c0054ec4 [ 2.048767] 5f00: ed8a4000 eeb9ac4c a0000053 00000000 ed845bc0 ed842440 c0054d80 00000000 [ 2.057342] 5f20: 00000000 00000000 00000000 c005999c 00000001 00000000 c05eaa64 ed842440 [ 2.065948] 5f40: 00000000 00000000 dead4ead ffffffff ffffffff c097c680 00000000 00000000 [ 2.074554] 5f60: c078acd4 ed8a5f64 ed8a5f64 00000000 00000000 dead4ead ffffffff ffffffff [ 2.083160] 5f80: c097c680 00000000 00000000 c078acd4 ed8a5f90 ed8a5f90 600000d3 ed845bc0 [ 2.091766] 5fa0: c00598d4 00000000 00000000 c000e668 00000000 00000000 00000000 00000000 [ 2.100341] 5fc0: 00000000 00000000 00000000 00000000 00000000 00000000 00000000 00000000 [ 2.108947] 5fe0: 00000000 00000000 00000000 00000000 00000013 00000000 90005148 11010482 [ 2.117553] [<c00548e0>] (process_one_work) from [<c0054ec4>] (worker_thread+0x144/0x498) [ 2.126159] [<c0054ec4>] (worker_thread) from [<c005999c>] (kthread+0xc8/0xe4) [ 2.133758] [<c005999c>] (kthread) from [<c000e668>] (ret_from_fork+0x14/0x2c) [ 2.141357] Code: e1a04001 e1a05000 e893000f e31e0004 (e5978004) [ 2.147766] ---[ end trace 5798e2803311b69f ]--- <snip> The final solution is to transition off to use 8250 driver and no dependency on console structures and move away from omap-serial driver, hence no major cleanups are done for this driver, so add a simple check to prevent future crashes in a similar manner in case of platform with additional ports.

Commit 479e9b94 ("serial: Refactor uart_flush_buffer() from uart_close") refactored the uart_flush_buffer() in uart_close() into those drivers that define a flush_buffer() method. However, in the amba-pl011 driver configured without CONFIG_DMA_ENGINE, flush_buffer() is a NULL method, so the direct call fails to compile. Check and call the flush_buffer() method through the ops table instead.

setup_serial_console() is obsolete and has been superseded by early_serial_setup() which is called at the end of the function. The IA64 arch does not call this function; only the m68k arch setup calls this function.
