2010-12-23	spi/topcliff_pch: Fix data transfer issue	Tomoya MORINAGA	1	-4/+4
	It seems spi_topcliff_pch of linux-2.6.37-rc6 degraded by previous patch. In fact, data transfer fails on evaluation board testing. I found like the following register miss-setting line. Using this patch, I have confirmed data transfer can work well. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-10-13	spi/topcliff: Fix uninitialized variable defect	Grant Likely	1	-1/+1
	This patch fixes the following build error introduced by commit 65308c46, "spi/topcliff: cleanup for style and conciseness". drivers/spi/spi_topcliff_pch.c: In function 'pch_spi_process_messages': drivers/spi/spi_topcliff_pch.c:752: warning: 'data' is used uninitialized in +this function Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2010-10-12	spi/topcliff: cleanups for style and conciseness	Grant Likely	1	-364/+138
	This patch makes multiple cleanups to the new topcliff pch spi driver including, but not limited to, - removing superfluous brackets around variables - open coding functions that are only used once - removing unnecessary line breaks - removing unused functions - simplifying the interrupt enable/disable code - remove unnecessary (void *) casts. - remove b_mem_fail from pch_spi_set_tx to code it more cleanly - shorten dev_dbg() messages for conciseness and readability More cleanups are still needed in this driver. In particular, - the driver filename should be changed to spi_topcliff_pch.c - many of the dev_dbg() lines should be trimmed (particularly the ones on unconditional code paths). - I suspect that the locking model not correct. I'd like to know what drivers' critical regions are, and how they are protected. - get_resources and release_resources probably should be open coded in .probe and .release respectively.

2010-10-08	spi/topcliff: Add topcliff platform controller hub (PCH) spi bus driver	Masayuki Ohtake	1	-0/+1529
	Topcliff PCH is the platform controller hub that is going to be used in Intel's upcoming general embedded platform. All IO peripherals in Topcliff PCH are actually devices sitting on AMBA bus. This patch adds a driver for the SPI bus integrated into the Topcliff device. Signed-off-by: Masayuki Ohtake <masa-korg@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
