spi-topcliff-pch: add recovery processing in case wait-event timeout

2012-05-21T17:46:24+00:00

commit 0f57e168aa109775430c76cc663fb64909813d84 upstream.

Currently, pch_spi_start_transfer failure is not anticipated.
This patch adds the processing.

spi-topcliff-pch: Fix issue for transmitting over 4KByte

2012-05-21T17:46:23+00:00

commit 7d05b3e868ee0f9231baf40cb77be3df5dd1f18c upstream.

Currently, when spi-topcliff-pch receives transmit request over 4KByte,
this driver can't process correctly. This driver needs to divide the data
into 4Kbyte unit.
This patch fixes the issue.

spi-topcliff-pch: fix -Wuninitialized warning

2012-04-22T22:39:17+00:00

commit de3bd7e6de25141c466773c2e0fa319b2fa93655 upstream.

Fix for:
drivers/spi/spi-topcliff-pch.c: In function ‘pch_spi_handler_sub’:
drivers/spi/spi-topcliff-pch.c:325:17: warning: ‘bpw_len’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘rx_index’ may be
  used uninitialized in this function [-Wuninitialized]
drivers/spi/spi-topcliff-pch.c:325:42: warning: ‘tx_index’ may be
  used uninitialized in this function [-Wuninitialized]

Move usage of tx_index, rx_index and bpw_len into the same
block as where they are set to prevent uninitialized usage.

v2: instead of init variables with 0 move the whole block

[This patch title "warnings" makes you think "This patch is not
for bug fix".  However, this patch surely patch for bug fix.]

Fix section mismatch in spi-pl022.c

WARNING: drivers/spi/built-in.o(.devinit.text+0xdb8): Section mismatch in reference from the function pl022_probe() to the function .init.text:pl022_dma_probe()
The function __devinit pl022_probe() references

The spi-s3c64xx driver is also used on Exynos4 so update the dependency
to enable build on those platforms.
