2017-07-28dm: core: add ofnode_count_phandle_with_args()Patrice Chotard
This function is usefull to get phandle number contained in a property list. For example, this allows to allocate the right amount of memory to keep clock's reference contained into the "clocks" property. To implement it, either of_count_phandle_with_args() or fdtdec_parse_phandle_with_args() are used respectively for live tree and flat tree. By passing index = -1, these 2 functions returns the number of phandle contained into the property list. Add also the dev_count_phandle_with_args() based on ofnode_count_phandle_with_args() Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Make SPL and (the full) U-Boot stage use independent SYS_MALLOC_F_LEN, so the size of pre-relocation malloc pool can be configured memory space independently.

2017-07-27rockchip: rk3288: Add support for drive-strength in PINCTRLRomain Perier
Currently, drive-strenght to 12ma are described and supposed to be used on RK3288. However, the pinctrl driver for this SoC only handles muxing and pull up/pull down via PU/PD control registers. So complex IPs like GMAC are working in normal ethernet 100mbps, but not at 1gbps typically. This commit adds support for handling drive-strength of 12ma, when it's defined in the DT.

auto-alloc The clk driver for the RK3368 picked the wrong data structure's size for its auto-alloc size: the size was calculated on the structure representing the CRU hardware block instead of the priv structure. As the CRU's register file is much larger than the driver's priv, this did not cause any pain (except wasting memory). Fix this by using the correct data structure's size.
