[PATCH/RFT 0/8] ARM: OMAP: remove IP checks from SoC family detection

[PATCH/RFT 0/8] ARM: OMAP: remove IP checks from SoC family detection

[Kevin Hilman]

This is a rebased version of this series which is ready for broader
testing.  I'd especially appreciate testing from those of you with
AM35x platforms.

Currently, our SoC detection is based on SoC family detection
(using die ID) and the presence of specific IP blocks (or feature.)

This series begins the separation of the SoC family detection and
specific IP detection by completely removing IP detection from the SoC
family detection (cpu_is_*.)

Applies on top of v3.4-rc4, boot tested on AM3517 EVM.

[PATCH/RFT 1/8] ARM: OMAP: remove unused cpu_is macros that depend on specific IP checks

[Kevin Hilman]

The cpu_is_omap35* macros for 3503, 3515, 3525) are unused.

Remove them in order to start removing IP detection from SoC family
detection.

[PATCH/RFT 2/8] ARM: OMAP3: clock data: replace 3503/3517 flag with AM35x flag for UART4

[Kevin Hilman]

The AM35x UART4 is common to all AM35x devices, so use CK_AM35XX instead
of (CK_3505 | CK_3517), which is equivalent.

[PATCH/RFT 3/8] ARM: OMAP3: clock data: treat all AM35x devices the same

[Kevin Hilman]

The init for 3505/3517 specific clocks depends on the ordering of
cpu_is checks, is error prone and confusing (there are 2 separate
checks for cpu_is_omap3505()).

Remove the 3505-specific checking since CK_3505 flag is not used, and
treat all AM35x clocks the same.

This means that the SGX clock (the only AM35x clkdev not currently
flagged for 3505) will now be registered on 3505, but that is
harmless.  That can be cleaned up when the clkdev nodes are removed in
favor of them being registered by hwmod.

[PATCH/RFT 4/8] ARM: OMAP: AM35x: remove redunant cpu_is checks for AM3505

[Kevin Hilman]

There are several checks for AM35x devices done using

      if (cpu_is_omap3517() || cpu_is_omap3505())

However, since the 3505 is just a 3517 without an SGX, the 3505 check
is redundant because cpu_is_omap3517() will always be true whenever
cpu_is_omap3505() is true.  From <plat/cpu.h>:

 #define cpu_is_omap3505() (cpu_is_omap3517() && !omap3_has_sgx())

Therefore, remove the redunant 3505 checks.  This helps move towards
removal of SoC detection that depends on specific IP detection.

[PATCH/RFT 8/8] ARM: OMAP: AM35xx: convert 3517 detection/flags to AM35xx

[Kevin Hilman]

Currently cpu_is_omap3517() actually detects any device in the AM35x
family (3517 and no-SGX version 3505.)  To make it more clear what is
being detected, convert the names from 3517 to AM35xx.

For the same reason, replace the CK_3517 flag used in the clock data
to CK_AM35XX.

Your series applied and booted without issue until the point that
pm_idle is called.  At that point it hung because its doing a wfi
and not getting an interrupt to wake up back up.  That's expected
behaviour so your patches are good (IMHO) but I need to finish and
submit a new version of my patches to fix that issue.

I tested using an nfs-mounted and mmc-mounted rootfs (and
CONFIG_TI_DAVINCI_EMAC=y).

For the benefit of others wanting to test this:

You have to use 'nohlt' on the cmdline on AM35x in order to avoid WFI
and the wakeup problems that are still being worked on.

No, since 3530 is the same as 3430 :(

Oops, yes.  I meant to add that and say that my am3517evm boots fine
with your patches and 'nohlt' on the cmdline.  I'm using omap2plus_defconfig
with CONFIG_TI_DAVINCI_EMAC enabled.

That happens later in the series.

Later in the series, it is renamed to cpu_is_am35xx().

Thanks for testing,  will add a Tested-by from you.

FYI... in order to avoid cross-tree dependencies going upstream, I split
this series up into two seprate series, and just posted them.  One for
just clocks for Paul[1]:

   [PATCH 0/3] ARM: OMAP3: clock: cleanup AM35xx clock flags

and another for converting most of the users of cpu_is_omap35*[2]:

   [PATCH 0/2] ARM: OMAP3: cleanup AM35xx SoC detection

Once these are merged, I have one more patch[3] (which depends on both of
the above branches) that will remove all the now unused cpu_is_omap35x*
defintions and the last remaining user in the clock code.

Subject: [PATCH] ARM: OMAP: SoC detection: remove unused cpu_is macros

Remove multiple unused cpu_is_omap35xx macros.

In particular, the cpu_is_omap35* macros for 3503, 3515, 3525 are removed
because they are using omap_has_* feature checks and we want to
remove specific feature detection from SoC family detection.

There are no longer any cpu_is_* checks that depend on specific IP
detection.
