[ Upstream commit d7faa8ffb6be57bf8233a4b5a636d76b83c51ce7 ]
In function rockchip_dt_node_to_map, a new_map variable is
allocated by:
new_map = devm_kcalloc(pctldev->dev, map_num, sizeof(*new_map),
GFP_KERNEL);
This uses devres and attaches new_map to the pinctrl driver.
This cause a leak since new_map is not released when the probed
driver is removed. Fix it by using kcalloc to allocate new_map
and free it in `rockchip_dt_free_map`

This fixes a problem with using the GPIO as an interrupt on Jaguar2
(and similar), as the register layout of the platforms with 64 GPIO's
are pairwise, such that the original offset must be multiplied with
the platform stride.

commit f354157a7d184db430c1a564c506434e33b1bec5 upstream.
Currently, for EINT_TYPE GPIOs, the CON and FLTCON registers
are saved and restored over a suspend/resume cycle. However, the
EINT_MASK registers are not.
On S5PV210 at the very least, these registers are not retained over
suspend, leading to the interrupts remaining masked upon resume and
therefore no interrupts being triggered for the device. There should
be no effect on any SoCs that do retain these registers as theoretically
we would just be re-writing what was already there.

commit b577a279914085c6b657c33e9f39ef56d96a3302 upstream.
Commit a8be2af0218c ("pinctrl: samsung: Write external wakeup interrupt
mask") started writing the eint wakeup mask from the pinctrl driver.
Unfortunately, it made the assumption that the private retention data
was always a regmap while in the case of s5pv210 it is a raw pointer
to the clock base (as the eint wakeup mask not in the PMU as with newer
Exynos platforms).
