b176654e77 OMAP: hwmod: Removal of macros for data that is obtained from hwmod database
Information like base address and DMA channel nubers should no longer
be obtained using macros. These information should be obtained from
hwmod database. Hence the macros that define the base address are removed.

2686e07b3e ASoC: McBSP: get hw params from McBSP driver
Removed the use of macros to obtain base address and DMA channel number.
Instead use the McBSP driver API's that passes base address and DMA
channel number to the client driver.

9504ba64f0 OMAP: McBSP: APIs to pass DMA params from McBSP driver to client drivers
After McBSP driver is hwmod adapted, the information about the hw would be
obtained from the hwmod database by the mcbsp driver. Since DMA programming is
handled by the client driver, APIs are provided to pass the DMA channel number
and base address of data register required by the client driver for DMA
programming.

f36d01d64f OMAP: McBSP: use omap_device APIs to modify SYSCONFIG
McBSP2/3 in OMAP3 has sidetone feature which requires autoidle
to be disabled before starting the sidetone. Also SYSCONFIG
register has to be set with smart idle or no idle depending on the
dma op mode (threshold or element sync). For doing these operations
dynamically at runtime, omap_device APIs are used to modify SYSCONFIG register.

e04d9e1e48 OMAP3: hwmod data: add DSS DISPC RFBI DSI VENC
Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and
OMAP36xx.  DSS is also considered as an IP as DISPC, RFBI and named as dss_core.
For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.

This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

e49c4d27ab omap: Add chip id recognition for OMAP4 ES2.1 and ES2.2
Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the
omap4_check_revision() function.

Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz).
ES2.2 additionally has a couple of power management fixes (to reduce
leakage), an I2C1 SDA line state fix, and a floating point write
corruption fix (cortex erratum).

Even though the current mainline support doesn't need to distinguish
between ES2.X versions, it's still useful to know the correct silicon
rev when issues are reported. Moreover, these id checks can be used by
power management code that selects suitable OPPs considering the
memory speed limitation on ES2.0.

c497dd5594 mtd: OneNAND: OMAP2: increase multiblock erase verify timeout
The current multiblock erase verify read timeout 100us is the maximum
for none-error case. If errors happen during multibock erase then
the specification recommends to run multiblock erase verify command
with maximum timeout 10ms (see specs. for KFM4G16Q2A and KFN8G16Q2A).

For the most common non-error case we wait 100us in udelay polling
loop. In case of timeout the interrupt mode is used to wait for the
command end.

OneNAND version ID may not give the highest frequency
supported and some OneNAND's have setup times that are
clock dependent.  Let the board provide that information.

OneNAND frequency is determined when calculating

1435ca0fc1 OMAP: OneNAND: fix 104MHz support
104MHz needs a latency of 8 clock cycles and the VHF
flag must be set.  Also t_rdyo is specified as
"not applicable" so pick a lower value, and force at
least 1 clk between AVD High to OE Low.

4b087ff857 omap3sdp: Fix regulator mapping for ads7846 TS controller
On the OMAP3430SDP board, the ads7846 touchscreen controller
is powered by VAUX3 regulator (supplying 2.8v).
Fix this mapping in the board file, and hence prevent
the ads7846 driver init to fail with the below error..

ads7846 spi1.0: unable to get regulator: -19

f040d33253 omap3: nand: making ecc layout as compatible with romcode ecc
This patch overrides nand ecc layout and bad block descriptor (for 8-bit
device) to support hw ecc in romcode layout. So as to have in sync with ecc
layout throughout; i.e. x-loader, u-boot and kernel.

This enables to flash x-loader, u-boot, kernel, FS images from kernel itself
and compatiable with other tools.

This patch does not enables this feature by default and need to pass from
board file to enable for any board.
