rev 1.01 (msm8992-lg-bullhead-rev-101.dts) has overclocking warnings: [ 1.997606] mmc0: Card appears overclocked; req 200000000 Hz, actual 343999999 Hz [ 1.997681] mmc0: Card appears overclocked; req 200000000 Hz, actual 343999999 Hz [ 2.010904] mmc0: Card appears overclocked; req 400000000 Hz, actual 687999999 Hz [ 2.012961] mmc0: Card appears overclocked; req 200000000 Hz, actual 343999999 Hz [ 2.027497] mmc0: Card appears overclocked; req 400000000 Hz, actual 687999999 Hz [ 2.027607] mmc0: Card appears overclocked; req 400000000 Hz, actual 687999999 Hz [ 2.039699] mmc0: new HS400 MMC card at address 0001 Similarly to angler use gcc GPLL4_EARLY to get rid of the warnings. Not tested on 1.0, but should work here as well. Signed-off-by: Petr Vorel <petr.vorel@gmail.com> --- @Jean: could you please test it on your rev 1.0? Thanks!
