mfd: remove htc-pasic3 driver

2023-02-01T16:29:30+00:00

The htc-pasic3 MFD device was only used in the PXA magician machine that is now removed, so this can be recycled as well. Cc: Lee Jones Cc: Philipp Zabel Acked-by: Robert Jarzmik Signed-off-by: Arnd Bergmann

mfd: Constify struct mfd_cell where possible

2014-01-06T09:13:29+00:00

As of commit 03e361b25ee8dfb1fd9b890072c23c4aae01c6c7 ("mfd: Stop setting refcounting pointers in original mfd_cell arrays"), the "cell" parameter of mfd_add_devices() is "const" again. Hence make all cell data passed to mfd_add_devices() const where possible. Signed-off-by: Geert Uytterhoeven Signed-off-by: Lee Jones

mfd: Use dev_get_platdata()

2013-07-31T12:01:29+00:00

Use the wrapper function for retrieving the platform data instead of accessing dev->platform_data directly. Signed-off-by: Jingoo Han Signed-off-by: Lee Jones

mfd: htc-pasic3: use module_platform_driver_probe()

2013-04-05T16:08:45+00:00

This patch uses module_platform_driver_probe() macro which makes the code smaller and simpler. Signed-off-by: Jingoo Han Signed-off-by: Samuel Ortiz

mfd: core: Push irqdomain mapping out into devices

2012-09-15T21:22:04+00:00

Currently the MFD core supports remapping MFD cell interrupts using an irqdomain but only if the MFD is being instantiated using device tree and only if the device tree bindings use the pattern of registering IPs in the device tree with compatible properties. This will be actively harmful for drivers which support non-DT platforms and use this pattern for their DT bindings as it will mean that the core will silently change remapping behaviour and it is also limiting for drivers which don't do DT with this particular pattern. There is also a potential fragility if there are interrupts not associated with MFD cells and all the cells are omitted from the device tree for some reason. Instead change the code to take an IRQ domain as an optional argument, allowing drivers to take the decision about the parent domain for their interrupts. The one current user of this feature is ab8500-core, it has the domain lookup pushed out into the driver. Signed-off-by: Mark Brown Signed-off-by: Samuel Ortiz

w1: ds1wm: add a reset recovery parameter

2011-07-09T04:14:44+00:00

This fixes a regression in 3.0 reported by Paul Parsons regarding the removal of the msleep(1) in the ds1wm_reset() function: : The linux-3.0-rc4 DS1WM 1-wire driver is logging "bus error, retrying" : error messages on an HP iPAQ hx4700 PDA (XScale-PXA270): : : : Driver for 1-wire Dallas network protocol. : DS1WM w1 busmaster driver - (c) 2004 Szabolcs Gyurko : 1-Wire driver for the DS2760 battery monitor chip - (c) 2004-2005, Szabolcs Gyurko : ds1wm ds1wm: pass: 1 bus error, retrying : ds1wm ds1wm: pass: 2 bus error, retrying : ds1wm ds1wm: pass: 3 bus error, retrying : ds1wm ds1wm: pass: 4 bus error, retrying : ds1wm ds1wm: pass: 5 bus error, retrying : ... : : The visible result is that the battery charging LED is erratic; sometimes : it works, mostly it doesn't. : : The linux-2.6.39 DS1WM 1-wire driver worked OK. I haven't tried 3.0-rc1, : 3.0-rc2, or 3.0-rc3. This sleep should not be required on normal circuitry provided the pull-ups on the bus are correctly adapted to the slaves. Unfortunately, this is not always the case. The sleep is restored but as a parameter to the probe function in the pdata.

w1: Use device platform_data to retrieve ds1wm platform bits

2011-05-26T17:45:00+00:00

With the addition of the platform device mfd_cell pointer, we can now cleanly pass the sub device drivers platform data pointers through the regular device platform_data one, and get rid of mfd_get_data(). Cc: Matt Reimer Cc: Philipp Zabel Signed-off-by: Samuel Ortiz
