MIPS: Alchemy: Fix cpu clock calculation

2015-03-06T22:52:54Z

commit 69e4e63ec816a7e22cc3aa14bc7ef4ac734d370c upstream. The current code uses bits 0-6 of the sys_cpupll register to calculate core clock speed. However this is only valid on Au1300, on all earlier models the hardware only uses bits 0-5 to generate core clock. This fixes clock calculation on the MTX1 (Au1500), where bit 6 of cpupll is set as well, which ultimately lead the code to calculate a bogus cpu core clock and also uart base clock down the line.

MIPS: Alchemy: DB1xxx: Explicitly set 50MHz clock for I2C/SPI units.

2014-09-22T11:35:47Z

Add an explicit call to set the desired rate to get the correct clock routing for the PSC clocks. It wasn't broken before, but now it's less affected by bootloader changes.

MIPS: Alchemy: devboards: sit and spin after poweroff

2014-09-22T11:35:46Z

On boards which don't support poweroff, systemd complains about this fact. In case poweroff fails, just sit and spin in the wait loop. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Cc: Manuel Lauss Patchwork: https://patchwork.linux-mips.org/patch/7558/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: Fix db1200 PSC clock enablement

2014-08-19T11:30:47Z

Enable PSC0 (I2C/SPI) clock and leave PSC1 (Audio) alone. This patch restores functionality to both Audio and I2C/SPI. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7544/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: remove old clock support

2014-07-30T12:12:00Z

With the clock framework in place, remove unused functions and bits, and drop the CLK_IGNORE_UNUSED flag, which is now unneeded. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7473/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: usb: use clk framework

2014-07-30T12:09:21Z

Add use of the common clock framework to set and enable the 48MHz clock source for the onchip OHCI and UDC blocks. Tested on a DB1500. (Au1200 and Au1300 use an external 48MHz crystal).
