The rtc-omap driver currently assumes that the rtc's
registers are at a fixed address and already mapped
into virtual memory space.  Remove those assumptions
so the same driver can be used for similar devices
that reside at different physical addresses (e.g.,
TI's DA8xx/OMAP-L13x SoC's).

Also allow the possibility for the timer and alarm
interrupts to use the same IRQ.

Suspend/resume support DA8xx/OMAP-L1xx frame buffer driver.
This feature has been tested on DA850/OMAP-L138 EVM. For the purpose
of testing, the patch series[1] which adds suspend support for
DA850/OMAP-L138 SoC was applied.

Add a helper function to enable raster. Also add one member in the
private data structure to track the current blank status, another
function pointer which takes in the platform specific callback function

These updates will help in adding suspend/resume and frame buffer blank

Implement memory accessor interface in the MTD layer which enables the
kernel to access flash data.

This patch adds two new members to the mtd_partition structure, a function
handler which will be called during setup of the partition and an argument
to be passed to this setup function.

Example:
+static struct mtd_partition spi_flash_partitions[] = {
+       [0] = {
+               .name       = "U-Boot",
+               .offset     = 0,
+               .size       = SZ_256K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [1] = {
+               .name       = "U-Boot Environment",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = MTD_WRITEABLE,
+       },
+       [2] = {
+               .name       = "Linux",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_7M,
+               .mask_flags = 0,
+       },
+       [3] = {
+               .name       = "MAC Address",
+               .offset     = MTDPART_OFS_NXTBLK,
+               .size       = SZ_64K,
+               .mask_flags = 0,
+               .setup      = davinci_get_mac_addr,
+               .context    = (void *)0,
+       },
+};

The davinci_get_mac_addr function reads the MAC address from
offset ZERO of last MTD partition.

  [PATCH] rc32434_wdt: fix compilation failure
  [WATCHDOG] rc32434_wdt.c: use resource_size()

On the parisc architecture we face for each and every loaded kernel module
this kernel "badness warning":
  sysfs: cannot create duplicate filename '/module/ac97_bus/sections/.text'
  Badness at fs/sysfs/dir.c:487

Reason for that is, that on parisc all kernel modules do have multiple
.text sections due to the usage of the -ffunction-sections compiler flag
which is needed to reach all jump targets on this platform.

An objdump on such a kernel module gives:
Sections:
Idx Name          Size      VMA       LMA       File off  Algn
  0 .note.gnu.build-id 00000024  00000000  00000000  00000034  2**2
                  CONTENTS, ALLOC, LOAD, READONLY, DATA
  1 .text         00000000  00000000  00000000  00000058  2**0
                  CONTENTS, ALLOC, LOAD, READONLY, CODE
  2 .text.ac97_bus_match 0000001c  00000000  00000000  00000058  2**2
                  CONTENTS, ALLOC, LOAD, READONLY, CODE
  3 .text         00000000  00000000  00000000  000000d4  2**0
                  CONTENTS, ALLOC, LOAD, READONLY, CODE
...
Since the .text sections are empty (size of 0 bytes) and won't be
loaded by the kernel module loader anyway, I don't see a reason
why such sections need to be listed under
/sys/module/<module_name>/sections/<section_name> either.

The attached patch does solve this issue by not exporting section
names which are empty.

The possible CCR_Y2K register values are 19 or 20 and struct rtc_time's
tm_year is in years since 1900.

The function translating rtc_time to register values assumes tm_year to be
years since first christmas, though, and we end up storing 0 or 1 in the
CCR_Y2K register, which the hardware does not refuse to do.

A subsequent probing of the clock fails due to the invalid value range in
the register, though.

[ And if it didn't, reading the clock would yield a bogus year because
  the function translating registers to tm_year is assuming a register
  value of 19 or 20. ]

This fixes the conversion from years since 1900 in tm_year to the
corresponding CCR_Y2K value of 19 or 20.
