Modified: trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.c trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.h Log: ar71xx: Add ath79_register_m25p80_large to support >16MB SPI chips The following patch is to add ath79_register_m25p80_large, which sets is_flash to false to support bit banging. This is needed on some 32MB+ SPI chips, such as the S25FL256S1 Signed-off-by: Chris R Blake <[email protected]> Modified: trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.c =================================================================== --- trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.c 2015-12-19 11:29:42 UTC (rev 47951) +++ trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.c 2015-12-19 11:32:20 UTC (rev 47952) @@ -106,6 +106,14 @@ register_mtd_user(¬); } +void __init ath79_register_m25p80_large(struct flash_platform_data *pdata) +{ + ath79_spi_data.bus_num = 0; + ath79_spi_data.num_chipselect = 1; + ath79_spi0_cdata.is_flash = false; + ath79_spi_info[0].platform_data = pdata; + ath79_register_spi(&ath79_spi_data, ath79_spi_info, 1); +} void __init ath79_register_m25p80_multi(struct flash_platform_data *pdata) { Modified: trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.h =================================================================== --- trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.h 2015-12-19 11:29:42 UTC (rev 47951) +++ trunk/target/linux/ar71xx/files/arch/mips/ath79/dev-m25p80.h 2015-12-19 11:32:20 UTC (rev 47952) @@ -12,6 +12,7 @@ #include <linux/spi/flash.h> void ath79_register_m25p80(struct flash_platform_data *pdata) __init; +void ath79_register_m25p80_large(struct flash_platform_data *pdata) __init; void ath79_register_m25p80_multi(struct flash_platform_data *pdata) __init; #endif /* _ATH79_DEV_M25P80_H */ _______________________________________________ openwrt-commits mailing list [email protected] https://lists.openwrt.org/cgi-bin/mailman/listinfo/openwrt-commits
