Some explanations: This patchset is to add SPI support in the existing spi_imx driver for i.MX51 and add SPI relating stuffs for mx51_3ds board level.
i.MX51 has two eCSPI controllers and one CSPI controller, CSPI controller is 100% compatible with the one of i.MX35, so we don't need to add new functions for this CSPI, only bind it with i.MX35 together, while eCSPI isn't compatible with existing controllers of i.MX platforms, so i add new functions for these two eCSPIs in the existing spi_imx driver. If these patches pass review, the first patch 0001-xxx.patch should be merged by Grant.likely; other patches(0002-0006) are based off imx-for-2.6.37 and should be handled by Sascha. On mx51_3ds board, there is a SPI NOR flash connected through eCSPI2, i have validated this patchset using this SPI NOR flash, see results: (bootlogs) <snip> m25p80 spi1.1: found sst25vf016b, expected m25p80 m25p80 spi1.1: sst25vf016b (2048 Kbytes) spi_imx spi_imx.1: probed <snip> (target tty console) # cat /proc/mtd dev: size erasesize name mtd0: 00200000 00001000 "spi1.1" # mtd_debug read /dev/mtd0 0 0x100 /a.txt Copied 256 bytes from address 0x00000000 in flash to /a.txt # hexdump a.txt 0000000 0000 eb00 0b53 eb00 002c e28f 0c00 e890 0000010 a000 e08a b000 e08b 7001 e24a 000b e15a 0000020 0000 1a00 0b4b eb00 000f e8ba e018 e24f 0000030 0001 e313 f003 1047 ff13 e12f 3720 0000 0000040 3730 0000 3000 e3b0 4000 e3b0 5000 e3b0 0000050 6000 e3b0 2010 e252 0078 28a1 fffc 8aff 0000060 2e82 e1b0 0030 28a1 3000 4581 ff1e e12f 0000070 e004 e52d 7000 e10f 700f e3c7 6001 e287 0000080 f006 e12f 0001 e040 d000 e1a0 6002 e287 0000090 f006 e12f 0001 e040 d000 e1a0 6006 e287 00000a0 f006 e12f 0001 e040 d000 e1a0 6007 e287 00000b0 f006 e12f 0001 e040 d000 e1a0 600b e287 00000c0 f006 e12f 0001 e040 d000 e1a0 600f e287 00000d0 f006 e12f 0001 e040 d000 e1a0 6003 e287 00000e0 60c0 e3c6 f006 e12f f004 e49d f003 e320 00000f0 ff1e e12f 4001 e92d 0f11 ee11 0001 e380 Thanks, Jason. ------------------------------------------------------------------------------ This SF.net Dev2Dev email is sponsored by: Show off your parallel programming skills.
