Most machine classes want some way to register a block of clk_lookup structures, and most do it by implementing a clks_register() type function which walks an array, or by open-coding a loop. Consolidate all this into clkdev_add_table().

For some platforms, it is inappropriate to register all PXA UARTs. In some cases, the UARTs may not be used, and in others we may want to avoid registering the UARTs to allow other drivers (eg, FICP) to make use of the UART. In addition, a while back there was a request to be able to pass platform data to the UART driver. This patch enables all of this by providing functions platforms can call to register each individual UART.

This is part of the work making gpio.c generic enough, the changes include: 1. move IRQ handling of GPIO 0 and 1 outside (and back into irq.c) 2. pxa_init_gpio() accepts a range for muxed GPIO IRQs, and an IRQ number for the muxed GPIOs 3. __gpio_is_occupied() and __gpio_is_inverted() are made inline, and are moved into <mach/gpio.h> instead of generic gpio.c Signed-off-by: NEric Miao <eric.miao@marvell.com>

Due to the problem of reset status bits being handled by different registers between pxa2xx and pxa3xx, introduce a global reset_status variable, initialized by SoC-specific code and later being used by other drivers. And also introduce clear_reset_status(), which is used to clear the corresponding status bits. Pass RESET_STATUS_ALL to clear all bits. Signed-off-by: NEric Miao <eric.miao@marvell.com>

The PXA25x and PXA27x USB device controller register definitions are different. Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.

Patch mainly from Eric Miao, with minor edits by rmk. Note: PWM0 and PWM2 share the same register I/O space and clock gating on pxa{27x, 3xx}, thus PWM2 is treated in the driver as a child PWM of PWM0. And this is also true for PWM1/3.

This makes the code better organized and simplified a bit. The change will lose a bit of performance when performing IRQ ack/mask/unmask,but that's not too much after checking the result binary. This patch also removes the ugly #ifdef CONFIG_PXA27x .. #endif by carefully not to access those pxa{27x,3xx} specific registers, this is done by keeping an internal IRQ number variable. The pxa-regs.h is also modified so registers for IRQ > PXA_IRQ(31) are made public even if CONFIG_PXA{27x,3xx} isn't defined (for pxa25x's sake) The incorrect assumption in the original code that internal irq starts from 0 is also corrected by comparing with PXA_IRQ(0). "struct sys_device" for the IRQ are reduced into one single device on pxa{27x,3xx}. Signed-off-by: Neric miao <eric.miao@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

According to PXA300/310 and PXA320 Developer manuals, the ASCR[RDH] "bit needs to be cleared as part of the software initialization coming out of any reset and coming out of D3". The latter requirement is addressed by commit "c4d1fb62", as for the former (coming out of any reset), the kernel relies on boot loaders and assumes that RDH bit is cleared there. Though, not all bootloaders follow the rule so we have to clear the bit in kernel. We clear the RDH bit in pxa3xx_init() function since it is always invoked after any reset. We also preserve D1S, D2S and D3S bits from being cleared in case we invoke pxa3xx_init() function not from normal hardware reset (e.g. kexec scenario), so these bits can be properly referenced later.
