I applied this to my v3.14/soc[1] branch. For some reason I could not
apply the patch to v3.11-rc1 (patch command returns error). Nothing is
obviously worng. Anyway, the change is minor so I made the change manually.

Thanks,
Sekhar

Re: [PATCH] i2c: davinci: raw read and write endian fix

 I2C IP block 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.

[PATCH] ARM: davinci: clock: return 0 upon error from clk_round_rate()

[Paul Walmsley]

clk_round_rate() should return 0 now upon an error, rather than returning 
a negative error code.  This is because clk_round_rate() is being changed 
to return an unsigned return type rather than a signed type, since some 
clock sources can generate rates higher than (2^31)-1 Hz.
