* memblock: stop using implicit alignment to SMP_CACHE_BYTESMike Rapoport2018-10-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When a memblock allocation APIs are called with align = 0, the alignment is implicitly set to SMP_CACHE_BYTES. Implicit alignment is done deep in the memblock allocator and it can come as a surprise. Not that such an alignment would be wrong even when used incorrectly but it is better to be explicit for the sake of clarity and the prinicple of the least surprise. Replace all such uses of memblock APIs with the 'align' parameter explicitly set to SMP_CACHE_BYTES and stop implicit alignment assignment in the memblock internal allocation functions. For the case when memblock APIs are used via helper functions, e.g. like iommu_arena_new_node() in Alpha, the helper functions were detected with Coccinelle's help and then manually examined and updated where appropriate. The direct memblock APIs users were updated using the semantic patch below: @@ expression size, min_addr, max_addr, nid; @@ ( | - memblock_alloc_try_nid_raw(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_raw(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid_nopanic(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid_nopanic(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc_try_nid(size, 0, min_addr, max_addr, nid) + memblock_alloc_try_nid(size, SMP_CACHE_BYTES, min_addr, max_addr, nid) | - memblock_alloc(size, 0) + memblock_alloc(size, SMP_CACHE_BYTES) | - memblock_alloc_raw(size, 0) + memblock_alloc_raw(size, SMP_CACHE_BYTES) | - memblock_alloc_from(size, 0, min_addr) + memblock_alloc_from(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_nopanic(size, 0) + memblock_alloc_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_low(size, 0) + memblock_alloc_low(size, SMP_CACHE_BYTES) | - memblock_alloc_low_nopanic(size, 0) + memblock_alloc_low_nopanic(size, SMP_CACHE_BYTES) | - memblock_alloc_from_nopanic(size, 0, min_addr) + memblock_alloc_from_nopanic(size, SMP_CACHE_BYTES, min_addr) | - memblock_alloc_node(size, 0, nid) + memblock_alloc_node(size, SMP_CACHE_BYTES, nid) ) [mhocko@suse.com: changelog update] [akpm@linux-foundation.org: coding-style fixes] [rppt@linux.ibm.com: fix missed uses of implicit alignment] Link: http://lkml.kernel.org/r/20181016133656.GA10925@rapoport-lnx Link: http://lkml.kernel.org/r/1538687224-17535-1-git-send-email-rppt@linux.vnet.ibm.com Signed-off-by: Mike Rapoport <rppt@linux.vnet.ibm.com> Suggested-by: Michal Hocko <mhocko@suse.com> Acked-by: Paul Burton <paul.burton@mips.com> [MIPS] Acked-by: Michael Ellerman <mpe@ellerman.id.au> [powerpc] Acked-by: Michal Hocko <mhocko@suse.com> Cc: Catalin Marinas <catalin.marinas@arm.com> Cc: Chris Zankel <chris@zankel.net> Cc: Geert Uytterhoeven <geert@linux-m68k.org> Cc: Guan Xuetao <gxt@pku.edu.cn> Cc: Ingo Molnar <mingo@redhat.com> Cc: Matt Turner <mattst88@gmail.com> Cc: Michal Simek <monstr@monstr.eu> Cc: Richard Weinberger <richard@nod.at> Cc: Russell King <linux@armlinux.org.uk> Cc: Thomas Gleixner <tglx@linutronix.de> Cc: Tony Luck <tony.luck@intel.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

* ARM: OMAP2+: Fix module address for modules using mpu_rt_idxTony Lindgren2018-08-17
| | | | | | | | | | | | | | | | | | If we use device tree data for a module interconnect target we want to map the control registers from the module start. Legacy hwmod platform data however is using child IP offsets for cpsw module with mpu_rt_idx. In cases where we have the interconnect target module already using device tree data with legacy hwmod platform data still around, the sysc register area is not adjusted for mpu_rt_idx causing wrong registers being accessed. Let's fix the issue for mixed dts and platform data mode by ioremapping the module registers using child IP offset if mpu_rt_idx is set. For device tree only data there's no reason to use mpu_rt_idx.

As we already have SmartReflex data configured, we use that as the first driver to enable. To do that in a way where SmartReflex is not probed twice, we need to prepare the SmartReflex driver before flipping dts data on for it in the last patch of the series. To avoid regressions, we are checking the passed dts data against existing platform data since we still have it available.

Note that we can make it use s8 instead of u8 as the hwmod code uses the feature flags to check for this field. However, for ti-sysc we can use -ENODEV to indicate a feature is not supported in the hardware and can simplify the code that way. And let's add also emufree_shift as the dts files will be describing the hardware for the SYSCONFIG register capbilities mask.

| | | | | | | | | | | | | | | | | | | | | | | | | When removing legacy platform data for IO ranges for the hwmod interconnect code, we still need to support the "ti,hwmods" property. And as we're going to use a generic sysc device driver to handle the interconnect target instances, we can parse the information needed for legacy "ti,hwmods" IO range from the dts. It's always the first range the interconnect target module provides. Note that we want to parse the range instead of the first child device IO regs as the child device may not always be defined. The child IP device node may not exist in cases where there is no driver binding for the device, or when the child IP block may not even be functional for some SoC revisions. But the IO range of the interconnect target module is always known.

First, the patch parses all "ti,clkctrl" compatible nodes and maps these against existing clockdomain data. Once done, individual hwmod init routines can search for a clkctrl clock handle based on the clockdomain info and the created mapping. This patch also drops the obsolete "_mod_ck" search as the implementation required for this was not accepted usptream.

Let's add this check into the _omap4_wait_target_ready/disable where we have access to both the clkctrl_offs and the flags values and simply return 0 without calling the low level CM call at all, which would have returned 0 anyway if the clktrl_offs was zero.

The main change here is to change the omap initcall levels a bit to initialize things later to allow early device drivers at core_initcall level. This makes things easier for us as most clocks can be made into regular device drivers except for a few early clocks needed to initialize system timers. I wanted to have these changes sit in Linux next for a few weeks before sending out a pull request, and so far now issues have showed up. The other changes in this series are timer changes for making use of the new PWM driver, and timer changes to support more high security SoCs. Also few minor improvments for module autoidle settings for ti81xx spinbox and dra7 debug on uart4 in hwmod code. The rest is pretty much just removal of platform data for SoCs that are all device tree only nowadays. * tag 'omap-for-v4.5/soc-initcall' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: Remove device creation for omap-pcm-audio ARM: OMAP1: Remove device creation for omap-pcm-audio ARM: OMAP2+: Change core_initcall levels to postcore_initcall ARM: DRA7: hwmod: Enable DEBUG_LL for UART4 ARM: OMAP: RX-51: fix a typo in log writing ARM: omap4: hwmod: Remove elm address space from hwmod data ARM: OMAP2+: timer: Remove secure timer for DRA7xx HS devices ARM: OMAP: dmtimer: check for fixed timers during config ARM: OMAP2+: Remove omap_mmu_dev_attr structure ARM: OMAP4: hwmod data: Remove legacy IOMMU attr and addrs ARM: OMAP3: hwmod data: Remove legacy IOMMU data ARM: OMAP2+: Remove legacy device instantiation of IOMMUs ARM: OMAP2+: Add hwmod spinbox support for dm816x ARM: OMAP: add DT support for ti,dm816-timer ARM: OMAP: dmtimer: Add clock source from DT Signed-off-by: Olof Johansson <olof@lixom.net>

This allows us to convert most of the clock drivers into regular device drivers. We only need a few minimal clock drivers early for the system timers to select between the 32KiHz clock and the high frequency oscillator. With these changes, initializing the clock drivers can be just done at core_initcall time with something like: np = of_find_node_by_name(NULL, "plls"); if (np) of_platform_populate(np, NULL, NULL, NULL); And then these clocks will be available for the interconnect code to use. Having most of the clock drivers being regular device drivers allows us to use the nice things like devm_* functions and dev_err and dev_dbg. As an extra bonus, this also allows us to develop the clock drivers for new SoCs as loadable modules initially for cases where we can boot up the system based on the bootloader configured clocks. To do this, let's change the core_initcalls to postcore_initcall under mach-omap2.
