Change the default Samsung LCD refresh from an unrealistic 117Hz to 50Hz
as no video applications on the HTC Magician can work that fast.
The optimalization lowers the RAM latency at least by 3%.

This patch optimizes initial values of the EGPIO chip driver.
GSM and sound should be powered off during boot. A weak accumulator and
a powered GSM sometimes cause a system reboot. A charging current should be
as high as possible during boot.

Cc: linux-kernel, linux-arm-kernel
This patch renames EGPIOs, which are used for the charging cable presence
and type detection. Old names did not correspond with an observed
functionality (on board_id 0x3a). The behavior is not:
- AC charger
- USB charger
- Cable detection
, but:
- AC/USB type
- Cable detection1
- Cable detection2
This patch fixes a possible typo in the bit offset for the cable detection
EGPIO declaration, too.

This patch changes fast_mode settings for the normal and power I2C
controller on the HTC Magician machine.
Connected device on the Power I2C:
- MAX1587A: working in the fast mode
Connected devices on the Normal I2C:
- UDA1380: working in the fast mode
- OV9640: bus became stuck in the fast mode
The OV9640 is not using a standard I2C protocol, but an SCCB variant. Maybe
it is not fully compatible in the fast mode. Therefore fast mode for normal
I2C is disabled. If you not using the OV9640 then you can enable the fast
mode for the UDA1380.

The pxaficp_ir driver requests a power GPIO for the transceiver internally,
so a global GPIO allocation in magician_init() is redundant.

Old definition for the physmap-flash driver is incomplete:
- Use of an EGPIO without previous request
- Missing the MTD partitions
This patch fixes it. Read functionality was tested on the machine with
board_id 0x3a. Writing was not tested.

USB host ports on the HTC Magician are wrongly enabled. Port 1 is for
bluetooth and port 2 is for OTG (mux in the charger connector).

HTC Magician contains a MAX1587A voltage regulator for a Vcore supply.
The Vcore regulation is required for a CPU speed switching. This patch adds
declaration for the max1586 driver.
Notice:
- MAX1587A version does not support the V6 (USIM) output.
- A boost resistor was directly measured for a board_id 0x3a.

Magician STUART port is connected to the infraport and used by the FICP
driver. The FICP driver uses its own definition.
Required for correct initialization of the pxaficp_ir driver after
planned dmaengine conversion.

This patch moves platform_add_devices() (standard declaration of devices)
outside of the platform specific device declarations. Moving to the end
of the magician_init() clarifies the source code (standard and specific

I still think these are a lot of arbitrary changes, maybe the

or something like this.

NAK on this one. Until this patch I can boot my o2 Xda mini with
Toppoly display and see the framebuffer kernel console output. Can we
split the LCD changes from the rest, I assume those are what breaks my
display.

Wouldn't that violate USB spec if we boot the magician while plugged

Just to be sure, please tell me what are the values of those three
EGPIOs while
a) wall plug charger plugged in
b) usb cable connected to a host plugged in
c) no cable plugged in
It could well be there are differences between our boards.

I have only ever tested the CSR bluetooth chip, so this could be
correct, or again something that is different between the magician

Fixed, not fake. Even though we can't control it, the backlight does
have a supply.

If your magician has USB client directly from PXA SoC (not external PHY),
then only host port 2 can be muxed with client.
Intel® PXA27x Processor Family, Developer’s Manual
"12.5 USB On-The-Go Operation"
"Figure 12-15. USB OTG Configurations"
I think there was no implementation in the Windows Mobile, but I was able to
switch this mux and use a wifi usb dongle on the same connector as USB client.

I read the Toppoly datasheet and it seems, the LCD panel implements V/HSYNC, while Samsung does not (and I'm sure at least one of these sync pins must be GPIO for DC-DC control). A solution is probably to reconfigure the GPIO muxes by detected LCD type.

You're right. As USB 2.0 device cannot draw more than 100mA until enumerated
(prior to battery charging spec 1.1). It is described in USB 2.0 specification,
chapter 7.3.2, in the table :
- Unconfigured Function/Hub - ICCInit - maximum 100mA.
So I'll drop this patch for now I think.
Cheers.

I'm still reluctant to have the reset with the timings handled in the board code
as I consider this should be in the camera driver code
(magician_camera_reset()).

It supports an actual state of the OV9640 driver handling. But I can exclude it until
OV9640 will be transitioned. I don't have enough information about gpiod and soc-camera
and not enough time to maintain multiple different (and dependent) patchsets.
I forgot to test the timings ... actually I think I forgot results :-D . It was around the same time
I have found I2C fast mode is not working. Will test again.

Well it is CPLD chip, so they can have different bitstreams (OT: I can think of many CPLD HDL enhancements :-D).
