MIPS: Loongson: Naming style cleanup and rework

2015-06-21T19:53:59+00:00

Currently, code of Loongson-2/3 is under loongson directory and code of
Loongson-1 is under loongson1 directory. Besides, there are Kconfig
options such as MACH_LOONGSON and MACH_LOONGSON1. This naming style is
very ugly and confusing. Since Loongson-2/3 are both 64-bit general-
purpose CPU while Loongson-1 is 32-bit SoC, we rename both file names
and Kconfig symbols from loongson/loongson1 to loongson64/loongson32.

MIPS: JZ4740: use Ingenic SoC UART driver

2015-06-21T19:53:26+00:00

Remove the serial support from arch/mips/jz4740 & make use of the new
Ingenic SoC UART driver. This is done for both regular & early console
output.

MIPS: JZ4740: introduce CONFIG_MACH_INGENIC

2015-06-21T19:52:47+00:00

In preparation for supporting Ingenic SoCs other than the JZ4740,
introduce MACH_INGENIC to Kconfig & move MACH_JZ4740 to a separate
entry selected by the board when appropriate. This allows MACH_INGENIC
to be used to enable things generic across Ingenic SoCs.

MIPS: Fuloong 2E: Replace CONFIG_USB_ISP1760_HCD by CONFIG_USB_ISP1760

2015-05-26T14:46:53+00:00

Since commit 100832abf065bc18 ("usb: isp1760: Make HCD support
optional"), CONFIG_USB_ISP1760_HCD is automatically selected when
needed.  Enabling that option in the defconfig is now a no-op, and no
longer enables ISP1760 HCD support.

Re-enable the ISP1760 driver in the defconfig by enabling
USB_ISP1760_HOST_ROLE instead.

Merge tag 'gpio-v4.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio

2015-04-18T12:22:10+00:00

Pull GPIO updates from Linus Walleij:
"This is the bulk of GPIO changes for the v4.1 development cycle:

- A new GPIO hogging mechanism has been added. This can be used on
boards that want to drive some GPIO line high, low, or set it as
input on boot and then never touch it again. For some embedded
systems this is bliss and simplifies things to a great extent.

- Some API cleanup and closure: gpiod_get_array() and
gpiod_put_array() has been added to get and put GPIOs in bulk as
was possible with the non-descriptor API.

- Encapsulate cross-calls to the pin control subsystem in
. Now this should be the only header any GPIO
driver needs to include or something is wrong. Cleanups
restricting drivers to this include are welcomed if tested.

- Sort the GPIO Kconfig and split it into submenus, as it was
becoming and unstructured, illogical and unnavigatable mess. I
hope this is easier to follow. Menus that require a certain
subsystem like I2C can now be hidden nicely for example, still
working on others.

- New drivers:

- New driver for the Altera Soft GPIO.

- The F7188x driver now handles the F71869 and F71869A variants.

- The MIPS Loongson driver has been moved to drivers/gpio for
consolidation and cleanup.

- Cleanups:

- The MAX732x is converted to use the GPIOLIB_IRQCHIP
infrastructure.

- The PCF857x is converted to use the GPIOLIB_IRQCHIP
infrastructure.

- Radical cleanup of the OMAP driver.

- Misc:

- Enable the DWAPB GPIO for all architectures. This is a "hard
IP" block from Synopsys which has started to turn up in so
diverse architectures as X86 Quark, ARC and a slew of ARM
systems. So even though it's not an expander, it's generic
enough to be available for all.

- We add a mock GPIO on Crystalcove PMIC after a long discussion
with Daniel Vetter et al, tracing back to the shootout at the
kernel summit where DRM drivers and sub-componentization was
discussed. In this case a mock GPIO is assumed to be the best
compromise gaining some reuse of infrastructure without making
DRM drivers overly complex at the same time. Let's see"

mips: ip32: add platform data hooks to use DS1685 driver

2015-04-17T13:04:11+00:00

This modifies the IP32 (SGI O2) platform and reset code to utilize the new
rtc-ds1685 driver.  The old mc146818rtc.h header is removed and ip32_defconfig
is updated as well.
