2019-06-19ARM: omap2: remove incorrect __init annotationArnd Bergmann1-1/+1
omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so we get a warning with clang-8: WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup() The function omap3xxx_prm_late_init() references the function __init omap3xxx_prm_enable_io_wakeup(). This is often because omap3xxx_prm_late_init lacks a __init annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong. When building with gcc, omap3xxx_prm_enable_io_wakeup() is always inlined, so we never noticed in the past.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/soc Driver changes for ti-sysc for v5.2 merge window This series of changes for ti-sysc interconnect target module driver gets us to the point where we can actually drop legacy platform data for many devices in favor of device tree data. To do this, we improve ti-sysc driver not to rely on platform data callbacks to manage module clocks, and handle more quirks needed for some devices. Also few minor fixes are needed, but were considered not needed to be sent separately as they only show up with this series. Then we drop several thousands of lines of legacy platform data for omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc, i2c, gpio and uart devices to start with as those are typically easily tested on all devices. In case of unexpected issues, we can just add back the legacy platform data for a single device type if needed. Finally we add initial support for enabling and disabling some devices without legacy platform data callbacks. I was planning on sending the dropping of legacy platform data as a separate series, but already applied Roger's patch on top and pushed it out. Note that this series depends on related SoC and is based on those. * tag 'omap-for-v5.2/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: (33 commits) bus: ti-sysc: Add generic enable/disable functions ARM: OMAP2+: Drop mcspi platform data for omap4 ARM: OMAP2+: Drop uart platform data for dra7 ARM: OMAP2+: Drop gpio platform data for dra7 ARM: OMAP2+: Drop i2c platform data for dra7 ARM: OMAP2+: Drop mmc platform data for dra7 ARM: OMAP2+: Drop uart platform data for omap5 ARM: OMAP2+: Drop gpio platform data for omap5 ARM: OMAP2+: Drop i2c platform data for omap5 ARM: OMAP2+: Drop mmc platform data for omap5 ARM: OMAP2+: Drop uart platform data for am33xx and am43xx ARM: OMAP2+: Drop gpio platform data for am33xx and am43xx ARM: OMAP2+: Drop i2c platform data for am33xx and am43xx ARM: OMAP2+: Drop mmc platform data for am330x and am43xx ARM: OMAP2+: Drop uart platform data for omap4 ARM: OMAP2+: Drop gpio platform data for omap4 ARM: OMAP2+: Drop i2c platform data for omap4 ARM: OMAP2+: Drop mmc platform data for omap4 Documentation: bus: ti-sysc: fix spelling mistakes "multipe" and "interconnet" bus: ti-sysc: Detect DMIC for debugging ...

We can just check for omap2 and 3 for i2c and smartreflex locally. The rest of the .rev data is already unused. Cc: Paul Walmsley <paul@pwsan.com> Cc: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-03-26ARM: OMAP2+: Allocate struct omap_hwmod based on dts dataTony Lindgren1-4/+78
With ti-sysc interconnect target module, we can allocate struct omap_hwmod data based on the devicetree data. This allows dropping the static SoC specific data eventually so we will only boot with data we actually need. To allocate struct omap_hwmod dynamically, we need to add a mutex for modifying the list, and remove __init for few functions. Note that we are not initialized oh->_clk or the optional clocks and their related quirks. That can be directly handled by the interconnect target module driver.

2019-03-26ARM: OMAP2+: Define _HWMOD_STATE_DEFAULT and use itTony Lindgren2-6/+7
For dynamically allocated struct hwmod entries probing with ti-sysc interconnect target module driver, we need to specify the initial default state the same way as we do for the platform data cases. Let's prepare for that by adding _HWMOD_STATE_DEFAULT that we can then use to set the initial default state without a need to add similar CONFIG_PM handling in multiple places.

2019-03-26ARM: OMAP2+: Prepare class allocation for dynamically allocated modulesTony Lindgren1-8/+10
For dynamically allocated sysconfig data we only need to allocate a new class for the cases where the class is shared. For dynamically allocated struct omap_hwmod we will always allocate a new class. Let's add detection for when we need to allocate a new class by comparing the class name against the module name. If they match, there's no need to allocate a new calls as we don't have case of mixed platform data and dts data initialized modules for the same class. Let's also move the init of class data inside the spinlock. Cc: Paul Walmsley <paul@pwsan.com> Cc: Tero Kristo <t-kristo@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2019-03-26ARM: OMAP2+: Fix potentially uninitialized return value for _setup_reset()Tony Lindgren1-1/+1
Commit 747834ab8347 ("ARM: OMAP2+: hwmod: revise hardreset behavior") made the call to _enable() conditional based on no oh->rst_lines_cnt. This caused the return value to be potentially uninitialized. Curiously we see no compiler warnings for this, probably as this gets inlined. We call _setup_reset() from _setup() and only _setup_postsetup() if the return value is zero. Currently the return value can be uninitialized for cases where oh->rst_lines_cnt is set and HWMOD_INIT_NO_RESET is not set.

2019-03-22ARM: OMAP2+: add missing of_node_put after of_device_is_availableJulia Lawall1-1/+3
Add an of_node_put when a tested device node is not available. The semantic patch that fixes this problem is as follows (http://coccinelle.lip6.fr): // <smpl> @@ identifier f; local idexpression e; expression x; @@ e = f(...); ... when != of_node_put(e) when != x = e when != e = x when any if (<+...of_device_is_available(e)...+>) { ... when != of_node_put(e) ( return e; | + of_node_put(e); return ...; ) } // </smpl> Fixes: e0c827aca0730 ("drm/omap: Populate DSS children in omapdss driver") Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Tony Lindgren <tony@atomide.com>
