This is important because on PXA3xx, the physical mapping of SMEMC registers differs from the one on PXA2xx. In order to get PCMCIA working on both PXA2xx and PXA320, the PCMCIA driver was adjusted accordingly as well. Also, various places in the kernel had to be patched to use __raw_read/__raw_write.

This patch introduces pxa2xx_map_io() and pxa3xx_map_io() to distinguish between PXA25x/PXA27x and PXA3xx memory mapping. Also, fixup for platforms broken after introducing pxa{25x,27x}_map_io() and pxa3xx_map_io() is included.

This patch extends the ASoC API to allow sound cards to have more than one CODEC and more than one platform DMA controller. This is achieved by dividing some current ASoC structures that contain both driver data and device data into structures that only either contain device data or driver data. i.e. struct snd_soc_codec ---> struct snd_soc_codec (device data) +-> struct snd_soc_codec_driver (driver data) struct snd_soc_platform ---> struct snd_soc_platform (device data) +-> struct snd_soc_platform_driver (driver data) struct snd_soc_dai ---> struct snd_soc_dai (device data) +-> struct snd_soc_dai_driver (driver data) struct snd_soc_device ---> deleted This now allows ASoC to be more tightly aligned with the Linux driver model and also means that every ASoC codec, platform and (platform) DAI is a kernel device. ASoC component private data is now stored as device private data. The ASoC sound card struct snd_soc_card has also been updated to store lists of it's components rather than a pointer to a codec and platform. The PCM runtime struct soc_pcm_runtime now has pointers to all its components. This patch adds DAPM support for ASoC multi-component and removes struct snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec or runtime PCM level basis rather than using snd_soc_socdev. Other notable multi-component changes:- * Stream operations now de-reference less structures. * close_delayed work() now runs on a DAI basis rather than looping all DAIs in a card. * PM suspend()/resume() operations can now handle N CODECs and Platforms per sound card. * Added soc_bind_dai_link() to bind the component devices to the sound card. * Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove DAI link components. * sysfs entries can now be registered per component per card. * snd_soc_new_pcms() functionailty rolled into dai_link_probe(). * snd_soc_register_codec() now does all the codec list and mutex init. This patch changes the probe() and remove() of the CODEC drivers as follows:- o Make CODEC driver a platform driver o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core. o Removed all static codec pointers (drivers now support > 1 codec dev) o snd_soc_register_pcms() now done by core. o snd_soc_register_dai() folded into snd_soc_register_codec().

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.

Considering the header mess ATM, it is not always possible to include the correct header files within board code. Let's keep this simple: <mach/pxa25x.h> - for pxa25x based platforms <mach/pxa27x.h> - for pxa27x based platforms <mach/pxa300.h> - for pxa300 based platforms <mach/pxa320.h> - for pxa320 based platforms <mach/pxa930.h> - for pxa930 based platforms NOTE: 1. one header one board file, they are not compatible (i.e. they have conflicting definitions which won't compile if included together). 2. Unless strictly necessary, the following header files are considered to be SoC files use _only_, and is not recommended to be included in board code: <mach/hardware.h> <mach/pxa-regs.h> <mach/pxa2xx-regs.h> <mach/pxa3xx-regs.h> <mach/mfp.h> <mach/mfp-pxa2xx.h> <mach/mfp-pxa25x.h> <mach/mfp-pxa27x.h> <mach/mfp-pxa3xx.h> <mach/mfp-pxa300.h> <mach/mfp-pxa320.h> <mach/mfp-pxa930.h> 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.

Related to d3930614. RCSR is only present on PXA2xx CPUs, not on PXA3xx CPUs. Therefore, we should not be unconditionally writing to RCSR from generic code. Since we now clear the RCSR status from the SoC specific PXA PM code and before reset in the arch_reset() function, the duplication in the corgi, poodle, spitz and tosa code can be removed.

Changes include: 1. rename MFP_LPM_WAKEUP_ENABLE into MFP_LPM_CAN_WAKEUP to indicate the board capability of this pin to wakeup the system 2. add gpio_set_wake() and keypad_set_wake() to allow dynamically enable/disable wakeup from GPIOs and keypad GPIO * these functions are currently kept in mfp-pxa2xx.c due to their dependency to the MFP configuration 3. pxa2xx_mfp_config() only gives early warning if MFP_LPM_CAN_WAKEUP is set on incorrect pins So that the GPIO's wakeup capability is now decided by the following: a) processor's capability: (only those GPIOs which have dedicated bits within PWER/PRER/PFER can wakeup the system), this is initialized by pxa{25x,27x}_init_mfp() b) board design decides: - whether the pin is designed to wakeup the system (some of the GPIOs are configured as other functions, which is not intended to be a wakeup source), by OR'ing the pin config with MFP_LPM_CAN_WAKEUP - which edge the pin is designed to wakeup the system, this may depends on external peripherals/connections, which is totally board specific; this is indicated by MFP_LPM_EDGE_* c) the corresponding device's (most likely the gpio_keys.c) wakeup attribute: Signed-off-by: Neric miao <eric.miao@marvell.com> Signed-off-by: NRussell King <rmk+kernel@arm.linux.org.uk>

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>
