From 2f1a74e5a2de0459139b85af95e901448726c375 Mon Sep 17 00:00:00 2001 From: eric miao Date: Wed, 21 Nov 2007 18:50:53 +0800 Subject: [ARM] pxa: make pxa2xx_spi driver use ssp_request()/ssp_free() 1. make pxa2xx_spi.c use ssp_request() and ssp_free() to get the common information of the designated SSP port. 2. remove those IRQ/memory request code, ssp_request() has done that for the driver 3. the SPI platform device is thus made psuedo, no resource (memory/IRQ) has to be defined, all will be retreived by ssp_request() 4. introduce ssp_get_clk_div() to handle controller difference in clock divisor setting 5. use clk_xxx() API for clock enable/disable, and clk_get_rate() to handle the different SSP clock frequency between different processors Signed-off-by: eric miao Signed-off-by: Russell King --- drivers/spi/Kconfig | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/spi/Kconfig') diff --git a/drivers/spi/Kconfig b/drivers/spi/Kconfig index abf05048c638..aaaea81e412a 100644 --- a/drivers/spi/Kconfig +++ b/drivers/spi/Kconfig @@ -153,6 +153,7 @@ config SPI_OMAP24XX config SPI_PXA2XX tristate "PXA2xx SSP SPI master" depends on SPI_MASTER && ARCH_PXA && EXPERIMENTAL + select PXA_SSP help This enables using a PXA2xx SSP port as a SPI master controller.
