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: au1100fb: use clk framework

2014-07-30T12:10:39Z

Use the clock framework to en/disable the clock to the au1100 framebuffer device. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7474/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: db1x00: use clk framework

2014-07-30T12:10:00Z

Make use of the clk framework to set up and enable all PSC clocks. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7469/ 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).

MIPS: Alchemy: platform: use clk framework for uarts

2014-07-30T12:09:02Z

Use the clock framework to get the rate of the peripheral clock. Remove the now obsolete get_uart_baud_base function. Signed-off-by: Manuel Lauss Cc: Linux-MIPS Patchwork: https://patchwork.linux-mips.org/patch/7468/ Signed-off-by: Ralf Baechle

MIPS: Alchemy: clock framework integration of onchip clocks

2014-07-30T12:08:42Z

This patch introduces common clock framework integration for all configurable on-chip clocks on Alchemy chips: - 2 or 3 PLLs which generate integer multiples of the root rate 12MHz, - 6 dividers which take one of the 3 PLLs as input and divide their rate by either multiples of 2 or 1 (Au1300). - another bank of up to 6 muxes which take either one of the 6 above dividers or one of the PLLs directly and divide their rate further by 1, 2, 3 or 4. - a few other sources which are used by onchip peripherals and are informational. This implementation will take the clock tree as it was set up by boot firmware: all in-kernel boards should continue to work without having to set up the clock tree in board code. CLK_IGNORE_DISABLED will be removed once all drivers have been converted.

MIPS: Alchemy: remove au_read/write/sync

2014-07-30T11:56:34Z

MIPS: Alchemy: add helpers to access static memory ctrl registers.

2014-07-30T11:53:52Z

This patch changes the static memory controller registers to offsets from base, prefixes them with AU1000_ to avoid silent failures due to changed addresses and introduces helpers to access them. No functional changes, comparing assembly of a few select functions shows no differences.

MIPS: Alchemy: introduce helpers to access SYS register block.

2014-07-30T11:53:28Z

This patch changes all absolute SYS_XY registers to offsets from the SYS block base, prefixes them with AU1000 to avoid silent failures due to changed addresses, and introduces helper functions to read/write them. No functional changes, comparing assembly of a few select functions shows no differences.
