2009-10-01ARM: 5731/2: Fix U300 generic GPIO, remove ifdefs from MMCI v3Linus Walleij2-0/+11
The #ifdefs in the MMCI driver were erroneous and just masking a bug in the U300 generic GPIO implementation. This removes the ifdefs and fixes the U300 generic GPIO instead. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-09-22ARM: 5720/1: Move MMCI header to amba include dirLinus Walleij1-2/+2
This moves the mmci platform data definition struct away from arch/arm/include/asm/mach/mmc.h into the more proper place among the other primecells in include/linux/amba/mmci.h and at the same time renames it to "mmci.h", and also the struct in this file confusingly named mmc_platform_data has been renamed mmci_platform_data for clarity.

2009-09-19ARM: 5678/1: SSP/SPI PL022 polarity terminology fixLinus Walleij1-1/+1
The definition of the SPI clock phase for the Motorola mode of the PL022 driver was incorrect: the spec had been interpreted as data being recieved on rising or falling edge of the clocks while the correct interpretation is that data can be recieved on the first or second edge transition, falling or rising depending on the polarity setting.

2009-09-19ARM: 5704/1: U300 sched_clock implementation v2Linus Walleij1-0/+15
This adds the long debated sched_clock() override for the weak in-kernel jiffybased sched_clock(). The implementation is more or less identical to the one used in arch/arm/plat-omap/common.c and at last attempt to merge this the merge was postponed at the request of Peter Zijlstra due to pending discussions regarding generalized clocksource-based sched_clock() implementations by adding a flag to the clocksource. However that discussion ended up with the generic code needing to be rewritten and Paul Mundt see no reason not to proceed with this for the time being as it can be easily converted once the generic code is in place.

2009-09-16ARM: 5698/1: MMCI pass capabilities in platform dataLinus Walleij1-0/+2
This makes it possible to pass down the host controller capabilities for the MMCI driver using the platform data. It also provides the capabilties for the U300 implementation as an example, and makes sure the 4bit wide mode is set if this is requested by the ios() now that we can actually set that capability for a platform.

2009-09-16ARM: 5580/2: ARM TCM (Tightly-Coupled Memory) support v3Linus Walleij1-0/+8
This adds the TCM interface to Linux, when active, it will detect and report TCM memories and sizes early in boot if present, introduce generic TCM memory handling, provide a generic TCM memory pool and select TCM memory for the U300 platform. See the Documentation/arm/tcm.txt for documentation. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2009-08-15ARM: 5673/1: U300 fix initsection compile warningLinus Walleij1-1/+1
The u300_init_check_chip() function was not properly tagged with the __init macro and provided a initsection mismatch on compilation. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-08-15ARM: 5668/2: U300 I2C board setupLinus Walleij4-2/+73
This sets up the U300 I2C subdevices so that the AB3100 analog baseband ASIC is properly detected and also the camera devices in the U335 reference design get properly registered. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-08-15ARM: 5667/3: U300 SSP/SPI board setup and testLinus Walleij6-0/+460
This adds a U300 board configuration for the PL022 SSP/SPI PrimeCell driver recently merged to the 2.6.31-rc series. Further it adds a dummy loopback SPI chip that can be used for testing the SPI functionality on a running system using the loopback mode of PL022.

2009-08-15ARM: 5666/1: Revamped U300 padmux APILinus Walleij4-60/+392
This abstracts the hackish padmux API on the U300 platform into something more manageable. It provides a way for drivers to activate/deactivate a certain padmux setting. It will also switch the users of the old API over to using the new style, pushing muxing into the apropriate setup files.

2009-08-15ARM: 5665/1: U300 syscon register updatesLinus Walleij1-7/+113
This adds in a few new register and defines for improved padmux support and some figures that were plain wrong on the targeted U300 platforms. Signed-off-by: Linus Walleij <linus.walleij@stericsson.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-07-09[ARM] 5594/1: Correct U300 VIC init PM settingLinus Walleij1-2/+2
This makes the VIC resume from suspend flagged IRQ:s identical to the flags indicating all possible interrupts. This is perhaps not the optimal setting but setting it to 0 makes the system suspend and never come back again (all IRQ sources masked off).

2009-07-09MMC: MMCI: allow GPIOs to be passedRussell King1-0/+2
Add and initialize the gpio_wp and gpio_cd members. We need to ensure that all users are covered, because GPIO 0 may be valid. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> Acked-by: Linus Walleij <linus.walleij@stericsson.com>
2009-07-02[ARM] 5581/1: U300 clock updatesLinus Walleij1-41/+80
This adds a few default locks to the clocks (the clocks were used before the locks were initialized by code), then renames the clocks a bit to fit with the latest driver names (some changed during review). Lastly it moves the initialization of the clock debugfs entry to module_init() initcall level since the debugfs isn't up in core_initcall().

2009-05-18[ARM] 5510/1: U300 GPIO debug and init fixesLinus Walleij1-22/+24
This moves the GPIO driver away from using __devinit and __devexit It also removes all printk() in favor of using dev_* print macros on pdev->dev struct instead. Surplus prints are removed, and the platform_device_probe() function is used instead of putting a .probe function in the platform driver struct.

2009-04-29[ARM] 5473/1: U300 core machine supportLinus Walleij15-0/+1716
This adds core support for the ST-Ericsson U300 series platforms: U300, U330, U335 and U365. Supports memory mappings, interrupt controller, system timer (clocksource and clockevents), and binds to the existing drivers for the PrimeCells used in this design: PL190 (VIC), PL180 (MMC/SD host) and PL011 (UART).
