ipq40xx: Add patches for 4.19 

This adds the necessary patches for 4.19 kernel.
Upstreamed patches were dropped, backported upstreamed patches
from 4.20.
Drop Winbond ID patch since that NAND IC was upstreamed to use
SPI-NAND framework and support for it was backported from 4.20.
Rework ESSEDMA patches to compile under 4.19 due to timer changes,
Clément Péron did the hard work and his changes were taken from the
initial 4.19 PR.
MR33 changes had to be manually refreshed to apply.
Refresh other patches to apply.

Subject: [PATCH] ARM: dts: qcom: ipq4019: fix cpu0's qcom,saw2 reg value
while compiling an ipq4019 target, dtc will complain:
regulator@b089000 unit address format error, expected "2089000"
The saw0 regulator reg value seems to be
copied and pasted from qcom-ipq8064.dtsi.
This patch fixes the reg value to match that of the
unit address which in turn silences the warning.
(There is no driver for qcom,saw2 right now.
So this went unnoticed)

This patch adds the gpio-ranges property to almost all of
the Qualcomm ARM platforms that utilize the pinctrl-msm
framework.
The gpio-ranges property is part of the gpiolib subsystem.
As a result, the binding text is available in section
"2.1 gpio- and pin-controller interaction" of
Documentation/devicetree/bindings/gpio/gpio.txt
For more information please see the patch titled:
"pinctrl: msm: fix gpio-hog related boot issues" from
this series.

To help with git bisect, the DT update patch has been intentionally
placed after the "pinctrl: msm: fix gpio-hog related boot issues".
Otherwise - if the order was reveresed - and bisect decides to split
between these two patches, the gpiochip_add_pin_ranges() function
will be executed twice with the same parameters for the same pinctrl.

Subject: [PATCH 2/2] clk: fix apss cpu overclocking
There's an interaction issue between the clk changes:"
clk: qcom: ipq4019: Add the apss cpu pll divider clock node
clk: qcom: ipq4019: remove fixed clocks and add pll clocks
" and the cpufreq-dt.
cpufreq-dt is now spamming the kernel-log with the following:
[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
for freq 761142857 (-34)
This only happens on certain devices like the Compex WPJ428
and AVM FritzBox!4040. However, other devices like the Asus
RT-AC58U and Meraki MR33 work just fine.
The issue stem from the fact that all higher CPU-Clocks
are achieved by switching the clock-parent to the P_DDRPLLAPSS
(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
as part of the DDR calibration.
For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
at round 533 MHz (ddrpllsdcc = 190285714 Hz).
whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
This patch attempts to fix the issue by modifying
clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
to use a new qcom_find_freq_close() function, which returns the closest
matching frequency, instead of the next higher. This way, the SoC in
the FB4040 (with its max clock speed of 710.4 MHz) will no longer
try to overclock to 761 MHz.

From 09ed737593f71bcca08a537a6c15264a1a6add08 Mon Sep 17 00:00:00 2001

Date: Sun, 20 Nov 2016 01:10:33 +0100
Subject: [PATCH] dts: ipq4019: add mdio node for ethernet
This patch adds the mdio device-tree node.
This is where the switch is connected to, so it's needed
for the ethernet interfaces.
Note: The driver isn't anywhere close to be upstream,
so the info might change.

Subject: [PATCH] dts: ipq4019: add PHY/switch nodes
This patch adds both the "qcom,ess-switch" and "qcom,ess-psgmii"
nodes which are needed for the ar40xx.c driver to initialize the
switch.
