Subject: [U-Boot] [PATCH v4 00/11] usb: Extend ehci and ohci generic drivers
Date: Wed, 24 May 2017 15:07:45 +0200 [thread overview]
Message-ID: <1495631276-25676-1-git-send-email-patrice.chotard@st.com> (raw)
From: Patrice Chotard <patrice.chotard@st.com>
This series improves generic ehci and ohci drivers by addition of :
_ error path during probe (clocks, resets and phy release)
_ .remove callback
_ add generic PHY framework for both generic ehci and ohci drivers
_ add RESET and CLOCK framework for generic ohci driver
To implement these features, some new methods are needed in RESET and
CLOCKS frameworks :
_ add reset_request(), reset_count() and reset_assert_all() methods in
RESET framework
_ add clk_count() and add clk_disable_all() methods in CLOCK framework
v4: _ add clk_disable_all() and reset_assert_all() methods into CLOCK and
RESET framework as suggested by Simon Glass and Marek Vasut
_ add reset_count() and clk_count() methods which returns respectively the
number of resets and clocks declared into "resets" and "clocks" DT properties.
This allows to allocate the right amount of memory to keep resets and clocks
reference
_ update the memory allocation for deasserted resets and enabled
clocks reference list. Replace lists by arrays.
v3: _ keep enabled clocks and deasserted resets reference in list in order to
disable clock or assert resets in error path or in .remove callback
_ add missing commit message
_ use struct generic_ehci * instead of struct udevice * as parameter for
ehci_release_resets() and ehci_release_clocks()
_ test return value on generic_phy_get_by_index() and
generic_phy_init()
_ split previous patch 5 in 3 independant patch for CLOCK, RESET and PHY support
v2: _ add needed reset_request() in RESET framework
_ add error path in ehci/ohci-generic to disable clocks and to assert
resets
_ add .remove callback with clocks, resets and phy release
_ split the replacement of printf() by error() in an independant patch
