When patches outside the series are in the target folder
KERNELPATCHDIR = "archive/sunxi- $ {KERNEL _ MAJOR _ MINOR}"
they create problems for all other patches in the series
and are difficult to move to the new kernel version because
they are not properly designed.
Move the patches to a separate development folder until
the design is fixed so that we can add them to the series.

On newer boards featuring the A523 SoC, the AXP323 (related to the
|
|
AXP313) is paired with the AXP717 and serves as a secondary PMIC
|
|
providing additional regulator outputs. However the mfd cells are all
|
|
registered with PLATFORM_DEVID_NONE, which causes the regulator cells
|
|
to conflict with each other.
|
|
|
|
Commit e37ec3218870 ("mfd: axp20x: Allow multiple regulators") attempted
|
|
to fix this by switching to PLATFORM_DEVID_AUTO so that the device names
|
|
would all be different, however that broke IIO channel mapping, which is
|
|
also tied to the device names. As a result the change was later reverted.
|
|
|
|
Instead, here we attempt to make sure the AXP313/AXP323 regulator cell
|
|
does not conflict by explicitly giving it an ID number. This was
|
|
previously done for the AXP809+AXP806 pair used with the A80 SoC.
