Hi everyone,
It took me a bit more than a month, but I finally put together a
second version (for v1 see [1]) of the Vybrid support patchset.
Some highlights of this version:
- Various code/commit arrangement feedback for v1 is addressed
- Added commit to move all of the i.MX clock code to drivers/clk
(Sascha, we'd probably have to coordinate with your i.MX6ul
patches on this one)
- I2C commit split in two
- clock tree is reconciled with Linux code, since having a custom
version of it proved to be difficult to compare agains Linux's
implementation
- GPIO driver (tested on a custom Vybrid board)
- FEC support (tested on a custom Vybrid board)
Any feedback is, as always, very much appreciated.
Thank you,
Andrey Smirnov

Some SoC (of which Vybrid is a one example) relegate GPIO direction
control to their pinmux IP block, instead of having that functionality
within GPIO IP. Add provisions to control that aspect of pinmux to
support such SoCs.

Port the clock dependency resolution algorithm utilized by Linux
kernel's version of of_clk_init(), to allow for SoCs whose DT clock
configuration reqires such behaviour for correct initialization (Vybrid
is one such example).

From: Andrey Smirnov @ 2016-11-09 16:13 UTC (permalink / raw)
To: barebox; +Cc: Andrey Smirnov
Move clk code from 'mach-imx' to 'drivers' to keep the code tree
structure closer to that of analogous one from Linux kernel and,
arguably although subjective, to keep 'mach-imx' less cluttered.

readb/writeb. This is needed to prepare driver code to support Vybrid
SoC's variant of this block.

CPU type is not a reliable indicator of the underlying type of IP core
used, since there's no 1:1 mapping between the two. As example of one
such violation consider Vybrid SoC which contains IP block from i.MX53.
Instead port feature flags from corresponding Linux kernel driver and
use the ones that are relevant.

Calling clk_get() with NULL as the second argument will give us "ipg"
clock as a result. The actual clock feeding into the peripheral is "per"
and, depending on the SoC, "ipg" and "per" may be separated by a clock
divider, so querying "ipg"'s rate may not result in rate that does not
represent the actual peripheral clock rate.
Change the code to request "per" as our peripheral clock to avoid
aforementioned problem.

Shadow memory does not have a true 1:1 mapping to fuse address
space. All i.MX6 devices, with exception of i.MX6SL have a 0x100 byte
gap between banks 5 and 6 (or addresses 0x2f and 0x30), so we need to
account for that when reading data from shadow memory.

For some i.MX variants more than just "ipg" clock need to be enabled for
Ethernet to function, so change the code to enable all of the clock
defined for FEC node (this is what analogous Linux driver does as well).

The series looks mostly good, but I won't find the time for a deeper
review anytime soon, so I decided to just give it a try in -next.

This patch breaks compilation on platforms using common clk but no
device tree, for example cupid_defconfig:
drivers/clk/clk-conf.c: In function '__set_clk_parents':
drivers/clk/clk-conf.c:41:3: error: implicit declaration of function 'of_clk_get_from_provider' [-Werror=implicit-function-declaration]
As this is not trivial to fix I dropped the rest of this series for now.
