The function cdns3_ep_config() calculates the maximum packet size based

for the corresponding Endpoint. This may result in a mismatch between
the maximum packet size programmed in the USB controller and the maximum

Additionally, since TD_SIZE is calculated in cdns3_ep_run_transfer() on the

sunxi board to try and avoid some regressions. This failed, so here are
some fixes for this.
This series adds support for Xilinx qspi parallel and
stacked memeories.
In parallel mode, the current implementation assumes that a maximum
of two flashes are connected. The QSPI controller splits the data
evenly between both the flashes so, both the flashes that are connected
in parallel mode should be identical.
During each operation SPI-NOR sets 0th bit for CS0 & 1st bit for CS1 in
nor->flags.
In stacked mode the current implementation assumes that a maximum of two
flashes are connected and both the flashes are of same make but can differ
in sizes. So, except the sizes all other flash parameters of both the flashes
are identical.
Spi-nor will pass on the appropriate flash select flag to low level driver,
and it will select pass all the data to that particular flash.
Write operation in parallel mode are performed in page size * 2 chunks as
each write operation results in writing both the flashes. For doubling the
address space each operation is performed at addr/2 flash offset, where addr
is the address specified by the user.
Similarly for read and erase operations it will read from both flashes, so
size and offset are divided by 2 and send to flash.

brcmnand controller can only access the flash spare area up to certain
bytes based on the ECC level. It can be less than the actual flash spare
area size. For example, for many NAND chip supporting ECC BCH-8, it has
226 bytes spare area. But controller can only uses 218 bytes. So brcmand
driver overrides the mtd oobsize with the controller's accessible spare
area size. When the nand base driver utilizes the nand_device object, it
resets the oobsize back to the actual flash spare aprea size from
nand_memory_organization structure and controller may not able to access

Add support for dumping a few of the clocks used on Qualcomm platforms.
Naming the Global PLL's, Root Clock Generators, and gate clocks.
This helps a lot with platform bringup and feature enablement by making
it easy to sanity check that the clocks are programmed correctly.
== Usage ==
Enable CONFIG_CMD_CLK and "#define LOG_DEBUG" at the top of
qcom-<soc>.c.
The "clk dump" command should print the states of all the gates, GPLLs
and RCGs for your SoC.
== Glossary ==
RCG: Root Clock Generator
* Takes in some fairly arbitrary high freq clock (configurable clock
source and options for taking just even pulses and other things)
* Output frequency = input_freq * (m/n) * (1/d) where m/n are arbitrary
8 or 16-bit values (depending on the RCG), and d is a number (with
support for .5 offsets).
GPLL: Global Phase Locked Loop
* Crystal as input
* integer multiplier + exponent part (2^-40)
Gate: Simple on/off clock
* Put between RCGs and the peripherals they power
* Required to allow for correct power sequencing
If you do the maths manually using the equations from "clk dump", the
numbers should roughly line up by they're likely to be out by a handful
of MHz. They output is formatted so that it can be pasted directly into
the python interpreter.
The bug in writing was caused by a long-standing error in the SPMI

So set the INTIA to send 80 clocks in esdhc_init_common and move

However, on 8MQ EVK and 8QXP MEK with some brands of SD cards, sending
80 clocks may not work well.
The root cause is related with power up time. According to spec, after
power stable, host shall supply at least 74 SD clocks to the SD card with
the maximum of 1ms. However, the power ram up time is related with the
characteristic of SD card. At the moment of sending 74 SD clocks, the
power probably not ram up to the operating level on the problematic
cards. Then cause the cards not ready.
This patch changes to send SD clock with 1ms duration to replace 80

This way meets the spec requirement as well, and adds the margin for

mmc: fsl_esdhc_imx: Enable AHB/IPG clk with clk bulk API
With partition reset supported for i.MX8QM/QXP/95 and etc, when linux
mmc runtime suspended, the mmc clks are gated off. While at same time
system controller reset Cortex-A cores because of various reasons(
WDOG timeout and etc), with SPL run again, only enable PER clk is not
enough, also need to enable AHB/IPG clk, here use clk bulk API to enable
all the clocks.
