|
|    of: Add helper function to check MMIO register endianness
|
|    SoC peripherals can come in several different flavors:
|
|     - little-endian: registers always need to be accessed in LE mode (so the
|       kernel should perform a swap if the CPU is running BE)
|
|     - big-endian: registers always need to be accessed in BE mode (so the
|       kernel should perform a swap if the CPU is running LE)
|
|     - native-endian: the bus will automatically swap accesses, so the kernel
|       should never swap
|
|    Introduce a function that checks an OF device node to see whether it
|    contains a "big-endian" or "native-endian" property.  For the former case,
|    always return true.  For the latter case, return true iff the kernel was
|    built for BE (implying that the BE MMIO accessors do not perform a swap).
|    Otherwise return false, assuming LE registers.
|
|    LE registers are assumed by default because most existing drivers (libahci,
|    serial8250, usb) always use readl/writel in the absence of instructions
|    to the contrary, so that will be our fallback.

usb: gadget: autostart: properly release f_multi_opts ...

the same as for usb gadget autostarter.

|
|    usb: gadget: properly release f_multi_opts
|
|    The usbgadget commands uses statically allocated f_multi_opts and passes
|    this to usb_multi_register(). These f_multi_opts are of course no
|    longer valid when we leave the usbgadget command. Luckily we do not use
|    the data after we left the usbgadget command, so this never has been a
|    problem. However, f_multi_opts has some allocated members which we can
|    not free anymore on gadget unregistration because we no longer have the
|    pointer to them.
|
|    Fix this by adding a release function to struct f_multi_opts. This way
|    we can allocate all memory dynamically and properly free it when not
|    used anymore.

MIPS: ath79: add initial QCA AR9344 SoC support ...

According to the documentation:
"The AR9344 is a highly integrated and feature-rich IEEE 802.11n 2x2 2.4/5 GHz
System-on-a-Chip (SoC) for advanced WLAN platforms.

It includes a MIPS 74Kc processor, PCI Express 1.1 Root Complex and Endpoint
interfaces, five port IEEE 802.3 Fast Ethernet Switch with MAC/PHY,
one MII/RMII/RGMII interface, one USB 2.0 MAC/PHY, and external memory
interface for serial Flash, SDRAM, DDR1 or DDR2, I2S/SPDIF-Out audio interface,
SLIC VOIP/PCM interface, two UARTs, and GPIOs that can be used for LED
controls or other general purpose interface configurations.
The AR9344 supports 802.11n operations up to 144 Mbps for 20 MHz and 300 Mbps
for 40 MHz respectively, and 802.11a/b/g data rates.
Additional features include Maximal Likelihood (ML) decoding, Low-Density
Parity Check (LDPC), Maximal Ratio Combining (MRC), Tx Beamforming (TxBF), and
On-Chip One-Time Programmable (OTP) memory."

clk: imx: cpu: don't store the address of a function parameter ...

The function imx_clk_cpu takes a const char *parent_name as second
paramter. The implementation introduced in commit 9a89ed9d281e then
uses the address of this function parameter to assign clk.parent_names.
This is an address on the stack that is saved in the clk tree and of
course this is easily overwritten by later execution paths of barebox.

Without this fix the clk_dump command reproducibly crashes on i.MX7
(which is the only SoC that makes use of imx_clk_cpu()).
