Re: [RFC 02/23] watchdog: omap_wdt: raw read and write endian fix
Hi Victor, Taras, From: Victor Kamensky victor.kamen...@linaro.org All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant. Signed-off-by: Victor Kamensky victor.kamen...@linaro.org Signed-off-by: Taras Kondratiuk taras.kondrat...@linaro.org This was added to linux-watchdog-next. Kind regards, Wim. -- To unsubscribe from this list: send the line unsubscribe linux-omap in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
