[PATCH 0/7] Generic RTC class driver

[Geert Uytterhoeven]

        Hi Alessandro et al,

This patch series:
  1. Adds the missing module alias to rtc-parisc (which is a bugfix), a=
nd
     performs a few cleanups,
  2. Moves the platform device creation out of rtc-ppc and into arch-sp=
ecific
     code (which is also a bugfix),
  3. Consolidates rtc-parisc and rtc-ppc into rtc-generic (which is a c=
leanup),
  4. Hooks up rtc-generic on m68k (it's been using [sg]et_rtc_time() si=
nce
     ages),
  5. Makes rtc-generic dependent on PARISC, PPC, and M68K (the existing
     [sg]et_rtc_time() users):
       a. without introducing ARCH_HAS_GENERIC_RTC,
       b. with a big fat warning in the Kconfig comment discouraging pe=
ople
          from relaxing the dependencies.
  6. Converts the PS3 RTC support into a separate driver, called rtc-ps=
3
     (as a bonus ;-)

To reduce code churn, the order and number of the actual patches slight=
ly
differs:
  [1] parisc: rtc: get_rtc_time() returns unsigned int
  [2] parisc: rtc: platform_driver_probe() fixups
  [3] parisc: rtc: Add missing module alias
  [4] parisc: rtc: Rename rtc-parisc to rtc-generic
  [5] m68k: Hook up rtc-generic
  [6] powerpc: Hook up rtc-generic, and kill rtc-ppc
  [7] powerpc/ps3: Add rtc-ps3

The rtc-parisc driver is not PA-RISC specific at all, as it uses the existing
(but deprecated) generic RTC infrastructure ([gs]et_rtc_time()).

[PATCH 5/7] m68k: Hook up rtc-generic

[Geert Uytterhoeven]

m68k has been a long time user of the generic RTC abstraction, so hook up
rtc-generic:
  - Create the "rtc-generic" platform device if mach_hwclk is set,
  - Add checks for mach_hwclk, in anticipation of RTC chip drivers being moved
    to drivers/rtc/.

  - Add checks for mach_hwclk, in anticipation of RTC chip drivers being moved
    to drivers/rtc/.

Fixed.

Ah, those pesky PPC-specific functions... switched to rtc_time_to_tm() and
rtc_tm_to_time().

All PS3-specific drivers have this. But there's an official PS3 platform
maintainer in MAINTAINERS.

From 41020647c3e2b07e0302a905a926d6221061a128 Mon Sep 17 00:00:00 2001

Subject: powerpc/ps3: Add rtc-ps3

Create a real RTC driver for PS3, and unhook the deprecated
ppc_md.[gs]et_rtc_time.

Fixed.

Ah, those pesky PPC-specific functions... switched to rtc_time_to_tm() and
rtc_tm_to_time().

All PS3-specific drivers have this. But there's an official PS3 platform
maintainer in MAINTAINERS.

Subject: powerpc/ps3: Add rtc-ps3

Create a real RTC driver for PS3, and unhook the deprecated
ppc_md.[gs]et_rtc_time.

I'll add the SH support once the patch set is merged, it's not a very
pressing matter, so no need to make the patch juggling any more

Please look at the MAINTAINERS file, that will give
the contact for PS3.  It is much easier to maintain
a single place for the contact than many spread
throughout the kernel sources.

Sorry, I hadn't been following the discussion closely, but
could you explain why we are going from a generic framework
where we hook in our platform specific part to a totally
independent driver that has such an increase in code size.

Why couldn't you fix the generic part so that udev could
load it automatically?

I much prefer to have this code in the platform support
code as it was.  It is much more effort (a pain) to maintain
a separate driver were I have to cater to a subsystem's
maintainer, and with this rtc it seems everyone who was
using the generic PPC driver will need to do the same.

 Having it in MODULE_AUTHOR allow my scripts to automatically
 send an email when appropriate.

 MAINTAINERS lists the files with an arbitrary
 driver title so that the search must be made by an human and there's
 no field that links a person to a specific .c .

 so every time I want to address someone I need to check MODULE_AUTHOR,
 the git log and the MAINTAINERS file.

I see.  It seems what you want is MODULE_MAINTAINER, as author is
the author, who after some time, may not be the maintainer any more.

There was some work by Joe Perches to list the files a maintainer is
responsible for into the MAINTAINERS file.  I think that would give
you what you want, a way to automatically get the maintainer of a
file.

Joe, could you let us know the status of that work?

I think it works fine, and is an acceptable
approach to finding a maintainer for either a
patch or a specific file.

The changes I've posted are probably not suitable
for merging by anyone other than Linus as
MAINTAINERS is the most heavily modified file
in the kernel tree.

I've submitted it several times after merging it
with the latest kernel without response from Linus.

I'd merge and submit it again if it could be accepted.

If someone would propose a mechanism that would
improve the possibility to get it merged, I'd
also appreciate that.

Alessandro prefers not to have generic RTC drivers on top of some other
abstraction, but wants platform/chip-specific drivers under drivers/rtc=
/
instead. The goal is to convert all RTC drivers buried in platform code
to separate RTC drivers.

(Alessandro, please correct me if I'm wrong)

BTW, I also fixed the generic part, which is now called rtc-generic and
autoloaded (patch 4).

They can keep on using rtc-generic for now (patch 6).

If you do not want rtc-ps3, you can nak it, and keep on using rtc-gener=

But please consider before doing that...
