[PATCH v9 0/3] MTD: at91: Add PMECC support for at91 nand flash driver

Josh Wu — 2012-05-26T13:24:34

Code is based on 3.4-rc2

Changes since v8,
use _relaxed read/write in most place. use writel in operations of Control Register since it needs memory barrier.
allocate the data for PMECC computation.
add pmecc prefix for related variable/functions.
modify code according to J.C's suggestion. except:
>> +for (i = 2; i <= 2 * host->cap; i += 2) {
> manage the j in the for loop
since that will change to: 
+for (i = 2, j = 1; i <= 2 * host->cap; i += 2, j = i / 2) {
it is not as simple as original one.

Changes since v7,
add time out for PMECC status reading.
modify the oobfree[0].offset to 2.
fix coding style.

Changes since v6,
split into 3 patches.
remove of_flat_dt_is_compatible() function. use additional dt parameter "has-pmecc".
refine the error handling code.
refine original atmel_nand_init_params() function.

Changes since v5,
add has_pmecc field to replace cpu_has_pmecc() function. Use compatible check in when proble.
simplify the pmecc_get_ecc_bytes() function.

Changes since v4

[STABLE PATCH] ARM: 7409/1: Do not call flush_cache_user_range with mmap_sem held

Will Deacon — 2012-05-25T14:38:04

From: Dima Zavin <dima< at >android.com>

commit 435a7ef52db7d86e67a009b36cac1457f8972391 upstream

We can't be holding the mmap_sem while calling flush_cache_user_range
because the flush can fault. If we fault on a user address, the
page fault handler will try to take mmap_sem again. Since both places
acquire the read lock, most of the time it succeeds. However, if another
thread tries to acquire the write lock on the mmap_sem (e.g. mmap) in
between the call to flush_cache_user_range and the fault, the down_read
in do_page_fault will deadlock.

[will: removed drop of vma parameter as already queued by rmk (7365/1)]

[PATCH 1/2] mtd mxc_nand: use 32bit copy functions

Sascha Hauer — 2012-05-25T14:22:41

The following commit changes the function used to copy from/to
the hardware buffer to memcpy_[from|to]io. This does not work
since the hardware cannot handle the byte accesses used by these
functions. Instead of reverting this patch introduce 32bit
correspondents of these functions.

From: Ludovic Desroches <ludovic.desroches< at >atmel.com>

It lets remove the Atmel specific workaround into arch/arm/kernel/irq.c used
to indicate to the AIC the end of the interrupt treatment.

[PATCH] [ARM] Unconditional call to smp_cross_call on UP crashes

Pantelis Antoniou — 2012-05-24T19:40:51

omap2plus_defconfig builds with SMP & SMP_ON_UP set.
On beagle (which is UP) is_smp() returns false and we don't call
smp_init_cpus which in turn does not initialize smp_cross_call which
remains NULL.

When issuing a reboot we OOPS with a NULL dereference on stop smp_call.

Fixed by checking is_smp in smp_send_stop()

Restarting system.

perf_event_v7.c compilation failure in next-20120523

(adds new entry to perf_event_v7.c)

b3426c5 ARM: perf: remove arm_perf_pmu_ids global enumeration

[PATCH] ixp4xx: fix compilation by adding gpiolib support

Richard Cochran — 2012-05-23T16:19:51

Once again, ixp4xx no longer even compiles. This patch fixes the issue
by converting over to gpiolib. This patch was first made by Imre and
posted by Marc, and I added in Russell's suggestion to empty the gpio
header file.

This fix should also go for 3.1, 3.2, 3.3, and 3.4.

modify the oobfree[0].offset to 2.
fix coding style.

Changes since v6,
split into 3 patches.
remove of_flat_dt_is_compatible() function. use additional dt parameter "has-pmecc".
refine the error handling code.
refine original atmel_nand_init_params() function.

Changes since v5,
add has_pmecc field to replace cpu_has_pmecc() function. Use compatible check in when proble.
simplify the pmecc_get_ecc_bytes() function.

Changes since v4,
fix typo and checkpatch warnings.
fix according to JC's suggestion. replace cpu_is_xxx() with DT
modify dt binding atmel nand document to add pmecc support.
tested in sam9263 without break hw ecc.
add ecc.strength.

Josh Wu (3):
  MTD: at91: extract hw ecc initialization to one function
  MTD: add dt parameters for PMECC
  MTD: atmel_nand: Update driver to support Programmable Multibit ECC controller

[PATCH] PINCTRL: SiRF: add CSR SiRFprimaII GPIO driver depending on pinmux APIs

Barry Song — 2012-05-22T07:14:05

From: Barry Song <Baohua.Song< at >csr.com>

In SiRFprimaII, Each GPIO pin can be configured as input or output
independently. If a GPIO is configured as input, it can also be
enabled as an interrupt source (either edge or level triggered).

These pins must be either MUXed as GPIO or other function pads. So
this drivers depend on pinctrl_request_gpio() API pinctrl-sirf.c
implements.
