From: Jean Delvare Date: Mon, 28 Apr 2008 09:15:16 +0000 (-0700) Subject: savagefb: speed up the I2C bus X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9201a8584c9bdb45b7b32cb3d2280c3dfbc76e39;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git savagefb: speed up the I2C bus There is no reason to drive the savagefb I2C bus at such a low speed, so bump it from 12.5 kbps to 50 kbps. The Intel (i810) and Matrox framebuffer drivers already run their I2C bus at this speed, and so are the legacy i2c-savage4 and i2c-prosavage drivers. Signed-off-by: Jean Delvare Cc: "Antonino A.
