mfd: madera: Allow more time for hardware reset

2020-01-24T07:33:58Z

Both manual and power on resets have a brief period where the chip will not be accessible immediately afterwards. Extend the time allowed for this from a minimum of 1mS to 2mS based on newer evaluation of the hardware and ensure this reset happens in all reset conditions. Whilst making the change also remove the redundant NULL checks in the reset functions as the GPIO functions already check for this. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Wait for boot done before accessing any other registers

2020-01-24T07:33:58Z

It is advised to wait for the boot done bit to be set before reading any other register, update the driver to respect this. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Add support for requesting the supply clocks

2019-11-11T08:45:03Z

Add the ability to get the clock for each clock input pin of the chip and enable MCLK2 since that is expected to be a permanently enabled 32kHz clock. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Fixup SPDX headers

2019-07-02T11:11:31Z

GPL-2.0-only is the preferred way of expressing v2 of the GPL, so switch to that. Remove some redundant copyright notices and correct some instances where the wrong comment type has been used in header files. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones

mfd: madera: Add Madera core support for CS47L92

2019-07-02T11:11:31Z

This patch adds all the core support and defines for the Cirrus Logic CS42L92, CS47L92 and CS47L93 smart audio CODECs. Registers or fields are named MADERA_* if it is part of the common hardware platform and does not conflict with any other Madera codecs. It is named CS47L15_* if it is unique to CS47L15 and conflicts with definitions on other codecs.

mfd: madera: Add supply mapping for MICVDD

2019-07-02T11:11:31Z

Currently we are relying on the exact match of the regulator name to find MICVDD, we should add an explicit supply mapping to allow this to be found more reliably. Signed-off-by: Charles Keepax Signed-off-by: Lee Jones
