2008-09-05[ARM] omap: convert OMAP drivers to use ioremap()Russell King1-4/+19
Signed-off-by: Russell King <[email protected]>
2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King1-3/+3
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <[email protected]>
2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King1-1/+1
Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h. Signed-off-by: Russell King <[email protected]>
2008-04-28spi: replace remaining __FUNCTION__ occurrencesHarvey Harrison1-2/+2
__FUNCTION__ is gcc-specific, use __func__ Signed-off-by: Harvey Harrison <[email protected]> Acked-by: David Brownell <[email protected]> Signed-off-by: Andrew Morton <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2008-04-11spi: fix platform driver hotplug/coldplugKay Sievers1-1/+3
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable SPI platform drivers, to allow module auto loading.

2007-10-16SPI driver runtime footprint shrinkageDavid Brownell1-5/+4
Shrink the runtime footprint of various SPI drivers: - Move the probe() routine into the init section where practical, using platform_driver_probe() to make that safe. This often saves around 1KB. Using platform_driver_probe() can also be a correctness fix, if the probe routine is already marked __init but the driver struct keeps a dangling pointer to it after init section removal. - Likewise move remove() routines into the exit sections. These changes would be inappropriate iff the platform devices were actually hotpluggable (e.g. they're found on optional addon cards, or in an FPGA that's dynamically reprogrammed). In these cases, that's not the situation; it's an SOC controller and the only device is initialized before these drivers.

2007-07-17SPI controller drivers: check for unsupported modesDavid Brownell1-0/+9
Minor SPI controller driver updates: make the setup() methods reject spi->mode bits they don't support, by masking aginst the inverse of bits they *do* support. This insures against misbehavior later when new mode bits get added. Most controllers can't support SPI_LSB_FIRST; more handle SPI_CS_HIGH. Support for all four SPI clock/transfer modes is routine.

2007-05-23omap_uwire: SPI_CPHA mode bugfixImre Deak1-2/+2
The omap_uwire controller driver handles SPI_CPHA incorrectly; It should mean: CPHA=0 ... sample at leading edge of clock CPHA=1 ... sample at trailing edge of clock This bug has been masked by inverse bugs in layered drivers; and was uncovered by running some of them on non-OMAP hardware.

2007-02-20[PATCH] SPI controller build/warning fixesDavid Brownell1-1/+1
The signature of the per-device cleanup() routine changed to remove its const-ness. Three new SPI controller drivers now need that change, to eliminate build warnings. This also fixes a build bug with atmel_spi on AT91 systems.

2007-02-12[PATCH] SPI controller driver for OMAP MicrowireDavid Brownell1-0/+572
This adds a SPI driver for the Microwire controller on OMAP1 chips. This driver has been used in the Linux-OMAP tree for some time now, including with some of those displays using standardized 9-bit commands followed by data with 8-bit words. Microwire only supports half duplex transfers, but that's all that most SPI protocols need. When full duplex, or higher speeds, are needed there are several other controllers that can be used on OMAP.
