Instead do the initial regmap setup with a minimal configuration only supporting physical I/O and then configure the cache once we have identified the device.

One is the normal bank, and the other one is the test bank, it means it have the same register address in the normal bank and test bank seperately. For test bank register, it needs a special I2C sequence to acess as below, Touching to 0xFA address Touching to 0xFB address Touching to 0xFF address Accessing bank register Touching to 0xFE address Touching to 0xFC address This sequence can't be interrupted. It means that we can't use i2c_transfef() to implement touching 0xFA address. Otherwise, other i2c operation may be inserted into 0xFA and 0xFB operation since the lock of i2c_adapter is already released.

This reverts commit 5dd7bf59e0e8563265b3e5b33276099ef628fcc7. Conflicts: scripts/mod/file2alias.c This change is wrong on many levels. First and foremost, it causes a regression. On boot on Assabet, which this patch gives a codec id of 'ucb1x00', it gives: ucb1x00 ID not found: 1005 0x1005 is a valid ID for the UCB1300 device. Secondly, this patch is way over the top in terms of complexity. The only device which has been seen to be connected with this MCP code is the UCB1x00 (UCB1200, UCB1300 etc) devices, and they all use the same driver. Adding a match table, requiring the codec string to match the hardware ID read out of the ID register, etc is completely over the top when we can just read the hardware ID register. --- arch/arm/mach-sa1100/assabet.c | 1 - arch/arm/mach-sa1100/cerf.c | 1 - arch/arm/mach-sa1100/collie.c | 8 +----- arch/arm/mach-sa1100/include/mach/mcp.h | 2 -- arch/arm/mach-sa1100/lart.c | 1 - arch/arm/mach-sa1100/shannon.c | 1 - arch/arm/mach-sa1100/simpad.c | 8 +----- drivers/mfd/mcp-core.c | 44 ++---------------------------- drivers/mfd/mcp-sa11x0.c | 7 ++--- drivers/mfd/ucb1x00-core.c | 48 ++++++++------------------------- drivers/mfd/ucb1x00-ts.c | 2 +- include/linux/mfd/mcp.h | 7 ++--- include/linux/mfd/ucb1x00.h | 5 +--- include/linux/mod_devicetable.h | 11 -------- scripts/mod/file2alias.c | 10 ------- 15 files changed, 21 insertions(+), 135 deletions(-) (limited to 'drivers/mfd') diff --git a/arch/arm/mach-sa1100/assabet.c b/arch/arm/mach-sa1100/assabet.c index d8aa1c28353b..0c4b76ab4d8e 100644 --- a/arch/arm/mach-sa1100/assabet.c +++ b/arch/arm/mach-sa1100/assabet.c @@ -202,7 +202,6 @@ static struct irda_platform_data assabet_irda_data = { static struct mcp_plat_data assabet_mcp_data = { .mccr0 = MCCR0_ADM, .sclk_rate = 11981000, - .codec = "ucb1x00", };

This occurs because two things happen: 1. When we suspended, we were woken up, and executed the loop. Finding that the touchscreen was not pressed, we prepare to schedule for a maximum timeout, before being stopped in try_to_freeze(). 2. an irq occurs, we disable the irq, and mark it as disabled, and wake the thread. This wake occurs while the thread is still within __refrigerator() 3. The thread is unfrozen, and __refrigerator() sets the threads state back to INTERRUPTIBLE. We then drop into schedule_timeout() with an infinite timeout and the IRQ disabled. This prevents any further screen touches activating the thread. Fix this by using kthread_freezable_should_stop() which handles the freezing issues for us outside of the hotspot where the task state matters. Include a flag to ignore the touchscreen until it is released to avoid sending unintended data to the application.
