The z2 machine calls pxa27x_set_pwrmode() in order to power off the machine, but this function gets discarded early at boot because it is marked __init, as pointed out by kbuild: WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode() The function z2_power_off() references the function __init pxa27x_set_pwrmode(). This is often because z2_power_off lacks a __init annotation or the annotation of pxa27x_set_pwrmode is wrong. This removes the __init section modifier to fix rebooting and the build error.

The pasic3-leds driver was never in vanilla kernel. Actual configuration data for a hypothetical driver does not describe hardware completely, so remove them. This patch prepare HTC Magician machine code to pasic3-leds driver addition. Signed-off-by:

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. Signed-off-by:

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 declaration are not mixed). Signed-off-by:

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. Signed-off-by:

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). Signed-off-by:

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. Signed-off-by:

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

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. Signed-off-by:

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%. Signed-off-by:

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.

Use a PWM lookup table to provide the PWM to the pwm-backlight device. The driver has a legacy code path that is required only because boards still use the legacy method of requesting PWMs by global ID. Replacing these usages allows that legacy fallback to be removed.
