2008-11-19S3C24xx NAND: allow for faster timingsHarald Welte
Tacls can actually be zero with some NAND flash devices, so we need to permit this. Also, the TACLS register actually specifies the actual number of HCLK clocks, where the TWRPH0 and TWRPH1 registers are auto-incremented by one HCLK clock in hardware.

This is a replacement for Atheros' HIF layer that uses the Linux SDIO stack. Using GPLv2, like Atheros' code this is based on. Work in progress. Not-Yet-Signed-off-by: Werner Almesberger <werner@openmoko.org>
2008-11-19ar6k-without-sdio.patchWerner Almesberger
Make the AR6000 WLAN driver compile after moving it outside the Atheros SDIO stack. Note that the config option's name changes as well. The choice of a non-standard location (drivers/ar6000/) is intentional. The driver is still very far from being in shape for mainline inclusion, and the odd location should serve as an immediate warning. Not-Yet-Signed-off-by: Werner Almesberger <werner@openmoko.org>

I hadn't realized at first that once could read the FIFO one byte at a time. The revised patch is below. - Werner ---------------------------------- cut here ----------------------------------- fix-s3c-nand-read-bytes.patch With the introduction of optimized OOB reads in nand_read_subpage, the length of the data requested may not be a multiple of four bytes. This caused a partial read on the 2440, leading to false ECC errors and, worse, attempts to "correct" them. Note that there is a similar issue in s3c2440_nand_write_buf, which doesn't seem to cause trouble yet. Signed-off-by: Werner Almesberger <werner@openmoko.org>

Subject: [PATCH] glamofb: Initialize only visible part of the memory. It takes lots of time (0.5 seconds) to initialize the whole memory. As only the visible part matters, we could just initialize that part. Signed-off-by: Chia-I Wu <olv@openmoko.com>
2008-11-19fix-mmc-busy-loop-on-bytes.patchWerner Almesberger
christer-mmc-byte-alignment.patch reduced the FIFO I/O granularity from words to bytes. This also includes the decision when the FIFO is empty or full. However, we sometimes only want to transfer full words, in which case do_pio_read/do_pio_write busy-loop until the FIFO has filled up or drained enough. In the case of do_pio_write, this can cause an endless loop if the amount of data exceeds the FIFO size, because do_pio_write runs before the transfer is initiated, so the FIFO never drains.

2008-11-19fix-lid302dl-bitbang-all-the-way-baby.patchAndy Green
This large patch removes motion sensor from Linux SPI bitbang driver. Previously, some access was done through Linux SPI protected by a mutex, and the ISR access was done by platform bitbang code due to inability of Linux SPI driver to work in the interrupt context. Now all access is done by bitbang callbacks in mach_gta02.c and are protected by single scheme of interrupt lockout for the duration -- I line-by-line'd the driver to confirm that best I could, adding protection and taking more care on several /sys related paths. Because this is no longer a Linux SPI bus driver, the path for various /sys things have changed. They can now be found down, eg, /sys/devices/platform/lis302dl.1/sample_rate lis302dl.1 is the top sensor and .2 the bottom. The names of the input susbsytem paths remain the same as before. Not working in interrupt context made trouble using interrupt lockout as locking [21474615.495000] BUG: sleeping function called from invalid context at kernel/sched.c:4684 [21474615.495000] in_atomic():0, irqs_disabled():128 [21474615.495000] 2 locks held by bash/779: [21474615.495000] #0: (&buffer->mutex){....}, at: [<c00ec1b0>] sysfs_write_file+0x30/0x80 [21474615.495000] #1: (pm_mutex){....}, at: [<c007a34c>] enter_state+0xd4/0x10c [21474615.495000] [<c0032a14>] (dump_stack+0x0/0x14) from [<c0049410>] (__might_sleep+0xdc/0xf8) [21474615.495000] [<c0049334>] (__might_sleep+0x0/0xf8) from [<c0316c38>] (wait_for_common+0x28/0x190) [21474615.495000] r5:c79ffd00 r4:c79ffd4c [21474615.495000] [<c0316c10>] (wait_for_common+0x0/0x190) from [<c0316e30>] (wait_for_completion+0x18/0x1c) [21474615.495000] r8:c79ffd84 r7:c79c4800 r6:c79ffd00 r5:c79ffd20 r4:c79ffd4c [21474615.495000] [<c0316e18>] (wait_for_completion+0x0/0x1c) from [<c01d28ec>] (spi_sync+0xa0/0xb8) [21474615.495000] [<c01d284c>] (spi_sync+0x0/0xb8) from [<c020ca10>] (__reg_write+0x88/0x94) [21474615.495000] [<c020c988>] (__reg_write+0x0/0x94) from [<c020cc30>] (lis302dl_resume+0x54/0x198) [21474615.495000] r6:60000013 r5:c79c4800 r4:c79bc9c0 [21474615.495000] [<c020cbdc>] (lis302dl_resume+0x0/0x198) from [<c01d2fb0>] (spi_resume+0x38/0x44) [21474615.495000] r6:00000010 r5:c79c4800 r4:c79c4974 [21474615.495000] [<c01d2f78>] (spi_resume+0x0/0x44) from [<c0198f34>] (resume_device+0x8c/0x1b0) [21474615.495000] [<c0198ea8>] (resume_device+0x0/0x1b0) from [<c01990c0>] (dpm_resume+0x68/0x134) [21474615.495000] r7:00000003 r6:00000010 r5:c79c4800 r4:c79c4974 [21474615.495000] [<c0199058>] (dpm_resume+0x0/0x134) from [<c01991b4>] (device_resume+0x28/0x38) [21474615.495000] r6:00000003 r5:c08b7188 r4:00000010 [21474615.495000] [<c019918c>] (device_resume+0x0/0x38) from [<c007a0f8>] (suspend_devices_and_enter+0x110/0x180) [21474615.495000] r4:00000000 [21474615.495000] [<c0079fe8>] (suspend_devices_and_enter+0x0/0x180) from [<c007a320>] (enter_state+0xa8/0x10c) [21474615.495000] r6:00000003 r5:c03aa414 r4:00000000 [21474615.495000] [<c007a278>] (enter_state+0x0/0x10c) from [<c007a430>] (state_store+0xac/0xc0) [21474615.495000] r6:c7b80000 r5:00000003 r4:c03aa414 [21474615.495000] [<c007a384>] (state_store+0x0/0xc0) from [<c014dfb4>] (kobj_attr_store+0x24/0x30) [21474615.495000] [<c014df90>] (kobj_attr_store+0x0/0x30) from [<c00ebe58>] (flush_write_buffer+0x54/0x68) [21474615.495000] [<c00ebe04>] (flush_write_buffer+0x0/0x68) from [<c00ec1d8>] (sysfs_write_file+0x58/0x80) [21474615.495000] r8:c7acca80 r7:c79fff78 r6:000be408 r5:00000004 r4:c7a19ea0 [21474615.495000] [<c00ec180>] (sysfs_write_file+0x0/0x80) from [<c00a91b8>] (vfs_write+0xbc/0x14c) [21474615.495000] [<c00a90fc>] (vfs_write+0x0/0x14c) from [<c00a9774>] (sys_write+0x4c/0x7c) [21474615.495000] r7:00000004 r6:00000000 r5:00000000 r4:c7acca80 [21474615.495000] [<c00a9728>] (sys_write+0x0/0x7c) from [<c002dc20>] (ret_fast_syscall+0x0/0x2c) Signed-off-by: Andy Green <andy@openmoko.com>
