| | * [ARM] pxa: Avoid pxa_gpio_mode() in gpio_direction_{in,out}put()Russell King2007-10-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | pxa_gpio_mode() is a universal call that fiddles with the GAFR (gpio alternate function register.) GAFR does not exist on PXA3 CPUs, but instead the alternate functions are controlled via the MFP support code. Platforms are expected to configure the MFP according to their needs in their platform support code rather than drivers. We extend this idea to the GAFR, and make the gpio_direction_*() functions purely operate on the GPIO level. This means platform support code is entirely responsible for configuring the GPIOs alternate functions on all PXA CPU types. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The PXA DMA support code for smc91x doesn't pass a struct device to the dma_*map_single() functions, which leads to an oops in the dma bounce code. We have a struct device which was used to probe the SMC chip. Use it. (This patch is slightly larger because it requires struct smc_local to move into the header file.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | a function pxa_init_irq_set_wake() was introduced, so that processor specific code could install their own version code setting PFER and PRER registers within pxa_gpio_irq_type are removed, and the edge configuration is postponed to the (*set_wake) and copies the GRER and GFER register, which will always be set up correctly by pxa_gpio_irq_type() Signed-off-by: eric miao <eric.y.miao@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
| | * [ARM] 4559/1: pxa: make PXA_LAST_GPIO a run-time variableeric miao2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This definition produces processor specific code in generic function pxa_gpio_mode(), thus creating inconsistencies for support of pxa25x and pxa27x in a single zImage. As David Brownell suggests, make it a run-time variable and initialize at run-time according to the number of GPIOs on the processor. For now the initialization happens in pxa_init_irq_gpio(), since there is already a parameter for that, besides, this is and MUST be earlier than any subsequent calls to pxa_gpio_mode().

| | * [ARM] 4550/1: sched_clock on PXA should cope with run time clock rate selectionNicolas Pitre2007-10-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The previous implementation was relying on compile time optimizations based on a constant clock rate. However, support for different PXA flavors in the same kernel binary requires that the clock be selected at run time, so here it is. Let's move this code to a more appropriate location while at it.

Make H4 use that. This should be easy to drop in to the OMAP1 boards using these debug cards; the only difference seems to be that the p2 does an extra reset of the smc using the fpga (probably all boards could do that, if it's necessary) and doesn't use the gpio mux or request APIs.
